So... The Clash had reggae and The Jam had soul....and in the face of what I would imagine (and you can partly hear) was a not entirely Tamla Motown-supportive crowd at the 100 Club in September 1977, the band let rip with the old soul numbers as encore.
What it lacks in the finesse of Ms D. Ross and Mr A. Conley it attempts to make up for in sheer old gutsy working class Surrey, er...SPUNK.
In short, 'here's a tune you might know'...
The Jam - 'Sweet Soul Music/Back In My Arms Again/Bricks & Mortar' (live at the 100 Club 11.09.77)
