I think the problem with Mo Tucker is that she sings this really shitty little nursery rhyme thing on the third Velvets album. I don't know if she sings any other stuff on their later albums.
Aww, After Hours is hands down my favourite song off that album, I can't really explain why I like it so much, I just thought it was the perfect ending.
Well, I like it too - its just not very, uh, good. Traditionally anyway. But then again, I suppose The Murder Mystery isn't either and its my favourite, so there you go!
