I've had this song going round and round in my head recently- I think it's Pete Astor's fault. She's My Best Friend was recorded by The Velvet Underground in May 1969 and wasn't good enough (!!!) to make any of their proper albums. Eventually it came out on VU in the 1980s as you surely know but it's pretty much as good as anything else the post-Cale group recorded. It demonstrates the brilliant simplicity of Lou Reed's song writing perfectly- and what's more it was sung by Doug Yule.
