big rock candy mountain

I used to listen to this cassette religiously when i was little (early 90's) and i haven't been able to find it. I just found out i'm pregnant and i would love to have this for my child. I know some songs on it, and it was also a story that ended with "now i lay me down to sleep." Other songs are big rock candy mountain and cockles and mussels. I really wish i could find this cassette (in CD form of course) so if anyone can help, it'd be appreciated.
