If you have ever listened to the original Stone the Crows or Robin Trower at his peak, then you've heard the voice of James Dewar. The Glasgow-born singer is one of a legion of great Scottish vocalists (including Frankie Miller, Tam White, Alan Ligertwood, Alan Gorrie and
Hamish Stuart) who brought a soulful passion to their music.
    Dewar's career began in the early 60s. While still a teenager he sang  and played bass in the Gleneagles alongside Alec Bell (guitar), Ross Nelson (guitar), Jimmy Smith (saxophone) and David Miller (drums). By 1963 they were the resident band at Glasgow's Lindella Ballroom but
their fortunes changed dramatically one night when a diminutive girl vocalist got up to sing with them. Marie McDonald McLaughlin Lawrie was barely fifteen, but her confidence was overwhelming. She joined the group, which quickly took another name inspired by the new arrival, Lulu and the Luvvers.
   The realigned unit then moved across town to the hipper Le Phonograph, where they became regulars. The club was owned by Tony Gordon, who had commercial ties in London. By February 1964 he had secured a deal for the group with Decca, and the result was Shout, one of  the  definitive singles of the Beat era. It deservedly reached the UK top ten, but interest in the tiny singer with a fishwife's roar obscured the punch the Luvvers brought to the songs. As interest became increasingly focused on Lulu, the role of the group diminished. Session musicians were used on later recordings and, despite working on one-night stands and package tours, disaffected Luvvers began to drift away. Jimmy Dewar left in 1965,  returning to Glasgow to rethink his career.
    By 1967 he could be found in a new band, Sock 'Em JB, an exciting unit  fuelled on material by Otis Redding, Sam and Dave, and Wilson Pickett. The vocalist was ex-Del-Jack Frankie Miller and the pianist John McGinnis, formerly of the Blues Council. (The latter act was one of the
finest Scotland produced, revolving around one-time Alex Harvey saxophonist Bill Patrick and Harvey's younger brother, Leslie. Sadly, two members were killed when their van crashed returning home to Glasgow from Edinburgh, and the despondent survivors split up.) Sock 'Em JB
were together for only a matter of months, ending when Miller formed a new group, Westfarm Cottage, en route to the Stoics. Dewar and McGinnis remained together and, by the following year, had formed a new tough-sounding band, blending blues and progressive rock. They were preparing to be the resident act at a new club, the Burns Howff,  when Leslie Harvey and Maggie Bell walked into a rehearsal. After a jam  it was suggested they join forces and Power was born.
   With Bell on vocals and Harvey on guitar, the unit gelled perfectly and  they quickly became one of Glasgow's most popular attractions. In 1969 Peter Grant, Led Zeppelin's manager, came to Glasgow to see them and within a matter of months they had won a management and recording
deal. Renamed Stone the Crows – and with the addition of ex-John Mayall  drummer Colin Allen – the group recorded two excellent albums, Stone the Crows and Ode to John Law.
    Bell's passionate voice and Leslie's fluid, economical style may have defined the band's music, but Dewar's role should not be underestimated.  His playing was always sympathetic and his earthy duets with Bell were genuinely moving.
   'He's one of the finest singers I've ever heard,' she said in a later interview. However, the axis of the band had moved – the singer and guitarist were also a couple – and both Dewar and McGinnis were unhappy with the diminished role they now played in the group they had formed. Both quit in February 1971.
   'I had to get Jimmy Dewar in a band', Frankie Miller told me in 1992.  'He was doing nothing in London.' The band in question was Jude, formed in July 1971. Miller had quit the Stoics, but Chrysalis, with whom he had a publishing deal, suggested he pair with guitarist Robin Trower, who
had recently left Procol Harum. With Dewar on bass and Clive Bunker (ex-Jethro Tull) on drums, Jude seemed like a marriage made in heaven, but it was not to be. 'I wanted to do the two-vocal thing,' Miller explained 'but the vehicle wasn't right. The best thing for Jimmy to do was to sing in
a power trio with Robin.'
    In September 1972, this is exactly what happened. A new group, dubbed 'Robin Trower', made its début in Vienna with a line-up completed by Dewar and drummer Reg Isadore. Two enthralling albums, Twice Removed From Yesterday and Bridge of Sighs, followed, on which Trower's  searing but melodic guitar work was matched by Jimmy's soulful voice, fully free at last to express emotion and empathy. Another former Procol member, Matthew Fisher, produced both sets and the understanding he showed with Robin and the group was clear to hear. By 1974 Robin Trower were established on the US circuit and when ex-Sly Stone drummer Bill Lordan replaced Isadore, a more rhythmic texture came to the fore. For Earth Below (1975), Live and Long Misty Days (both 1976) ensued before another ex-Sly member, Rusty Allen, took over on bass to allow Dewar to concentrate on vocals. In City Dreams (1977) and Caravan to Midnight (1978) were completed before Allen quit and the group reverted to a trio for Victims of the Fury (1980) and Back It Up in 1983.
