I got a Czechoslovakian mandolin, a bongo, Peggy Seeger's 1967 "how to play the 5-string banjo" book, Nonesuch Explorer's "Koto Classics" CD and some classical guitar tuition books for 25 quid a month ago from Brixton Dr Barnardo's.
The other day I got W.H. Davie's book 'Autobiography of a Super Tramp", which I've always meant to get round to reading, a so-bad-it's-good potboiler paperback bio of Frank Sinatra and a nice Margaret Howell shirt that fits really well.
Brixton Dr Barnardo's seems to get a lot of promo CDs on account of all the music PR firms who rent office space in Bon Marché
