Vocal Voices

I don't know if I dare tell this one!

I've been waiting for the perfect moment to tell a joke about an Elvis song, so here goes? I suppose that -

It's now or never.

Seems like you're caught in a trap, are you all shook up?

Maybe you're a bit lonesome tonight, but don't go crying in the chapel, a bit of fun in Acopulco might help.

Having read that, my thought was simply "Return to Sender" !
