Wow! I did not know that. Harry made it his own. I've never heard any other versions, have you?
I had known that Harry wasn’t the writer of Without You (or of his other greatest hit, Everybody’s Talkin’), but until looking it up tonight I hadn’t know it was by the Badfinger guys. And I haven’t heard any other versions, not even the one by Mariah Carey that was apparently a big hit in the ‘90s.
