“It was Aretha Franklin who made Don Cornelius realise he had hit the big time,’ (The Guardian). “Just two years earlier, the impresario’s show Soul Train had been a Chicago thing, broadcasting local talent to local viewers. Now it was a national sensation and even the choosiest stars wanted to get on board. Franklin told him: ‘My kids love the show and I want to be a part of it.’ Stevie Wonder improvised an ode to Soul Train. James Brown, convinced that somebody, probably a white somebody, must be behind such a slick operation, looked around its Los Angeles studio and kept asking Cornelius: ‘Brother, who’s backing you on this?’ Each time Cornelius replied: ‘Well, James, it’s just me.’
He wasn’t bragging. As the host (or ‘conductor’) of Soul Train from 1970 to 1993, Cornelius was an avatar of cool, with his glorious afro, wide-lapelled suits and avuncular baritone, signing off each episode with a funky benediction: ‘I’m Don Cornelius, and as always in parting, we wish you love, peace … and soul!‘ Billed as ‘the hippest trip in America,’ Soul Train didn’t just beam the latest sounds from black America into millions of homes, but – with amateur dancers who became as integral to the show as the performers – the fashions, hairstyles and dance moves too.”
The theme for the show, “‘TSOP (The Sound of Philadelphia)’ is a 1974 recording by MFSB featuring vocals by The Three Degrees,” (Billboard). “It was written by Gamble and Huff … (and) was the first television theme song to reach No. 1 on the Billboard Hot 100.” The track also went to #1 on Billboard‘s Easy Listening chart and Hot Soul Singles chart, as well as reaching top 20 positions in many countries worldwide.
After a start in C major, the tune shifts to C minor from 0:33 – 1:07 before returning to original key. The track continues to alternate between the two parallel keys throughout, keeping the groove front and center at all times.
