I've always known Little Anthony's version from the album. It's an immense Teddy Randazzo production. But more than that, I've always felt there's a haunting element to the vocal that lifts it up further. It may of come naturally to Little Anthony, it may not of been intended - but there are nuances in his performance of this in that version on the album, that I can still recall and were they on replaying this morning. I like other versions, the Delfonics is good as said. Always want to hear Willie Hutch or Baby Washington, but it's the Little Anthony version that's stayed with me.
