Not chart related but in B&S mag back in the day ..........
... the Contempo Soul Source Section, where you could purchase the records on offer each edition.
In B&S #82 (April 72) they put on offer a self selection soul pack -- 10 US 45's for £1 (what a rip off even though P&P was included !!).
The selection on offer at that time included :-
Markeys "Knock On Wood"; Staple Singers "The Ghetto"; Judy Clay "It Ain't Long Enough"; Margie Joseph "One More Chance"; Darrell Banks "I'm The One Who Loves You"; Jimmy Hughes "Chains Of Love"; Johnny Taylor & Carla Thjomas "Just Keep On Lovin Me"; Billy Harner "She's Almost You"; Dells "Always Together"; Blinky "I Wouldn't Change The Man He Is" PLUS other 45's from Chuck Jackson, Shorty Long, Inez Foxx, Howard Tate, 4 Tops, Impressions, David Ruffin, Ramsey Lewis and more.
You'd have been hard pushed to have picked a good quid's worth out of those ?!?!?!
Still, if you couldn't find 10 you wanted, you could order them individually at 20p each.
