Wiki on the song. Probably my favourite Patti Smith songs. Well not really a song. A poem set to music. Here
Wiki says: The song describes the helpless alienation Smith felt while working on a factory assembly line and the salvation she dreams of achieving by escaping to New York City.[1]
Patti Smith was in Bath and went into a pub for lunch. I won't name the pub. Ordered lasagne. They gave her the wrong dinner - a shepherd's pie and she started eating it. The pub realised their mistake and were angry about her starting it as it meant they couldn't use it and shouted at her. She burst into tears.
