For those of you who like Steeleye Span but not folk music (!) - here is an encore piece from their early years - with Martin Carthy singing lead in an a cappella version of Buddy Holly's Rave On.
Note: This is my son's favourite Steeleye track - which is rather a back-handed compliment I would think!
Further note: Blogger will not let me embed YouTube videos at present, presumably due to some kind of update/ improvement. These things generally get sorted out - eventually...
