I heard it at the Boston red sox game the other night all I can remember is that is started with a strange mix at the start then the first line of the song was "out here in the field" old rock song maybe?

Ah! Yes!
Out Here in the Fields I fight for my meals!
I get My back into my living!.

Yep! Old Rock Tune by the WHO

Sung by Roger Daltry
Possibly written by Peter Townsend

Called "Teenage Wasteland"

Ah! Yes! The Memories!

I think I remember hereing that song in an animated movie about animals once, if you have, can you tell me which one?
