I may be late to notice but anyway...

I was having a friend listen to BJ earlier today and when he heard bad name he said:"Hey, this sounds like Bonnie Tyler's If You Were a Woman!", so we downloaded it and indeed the two chorus sound very much the same. So we checked the dates these singles came out to check who might have stolen the other and guess what, both came out in 1986 and were written and/or co-written by... Desmond Child.
I'd never thought this guy's influence would have made BJ sound like Bonnie Tyler for anyone.
