Soft Cell's Tainted Love

[tenaya]

I've started to figure out iTunes and have dl'd a couple of songs, including Tainted Love. I bought the 7" single version but it's not the version I hear on the radio or jukeboxes. Does anyone know which version ends with a few bars of another song tacked on the end? I can't think of it's title, I think it's a Motown song though.

Thanks!
