In this episode we welcome the great soul scribe Tony Cummings to Hammersmith to discuss the subject of his classic 1975 book The Sound of Philadelphia.

Tony travelled all the way down from his adopted Stoke-on-Trent to answer our questions about his earliest musical passions in his native Plymouth and the launch of his pioneering '60s fanzines Soul, Soul Music and Shout. He goes on to talk about his contributions to (and editorship of) Black Music magazine – and his deep immersion in the "Philly Soul" sound patented by Kenny Gamble, Leon Huff and Thom Bell. We hear about the extraordinary stable of musicians who performed on timeless hits by acts such as the O'Jays, the Three Degrees and Harold Melvin & the Blue Notes.

Clips from audio interviews with Kenny Gamble and – from 1976 – the Stylistics' Herb Murrell prompt reflections on the lavish sound and sophistication of R&B classics by everyone from the Delfonics and Jerry Butler to Teddy Pendergrass and McFadden & Whitehead.

Many thanks to special guest Tony Cummings.
