Thanks, Cereal Killer. Damn, a group that big I should have remembered.
Anyway, here's another one:
Tell Him by the Exciters.
I know something about love. You've gotta want it bad
If that guy's got into your blood, go out and get him
If you want him to be the very part of you

[Reff:]
Tell him that you're never gonna leave him
Tell him that you're always gonna love him
Tell him, tell him, tell him, tell him right now

Doo Wah Diddy played on the radio in America, how the heck did an English band get hold of the record in order to remake it?
