Yup, I've heard 'em both, and I'd have to say Carlos did a substantial amount of "borrowing". As to his motives (assuming he WAS conscious of it...and I'm not convinced of that) who knows? Has there been anything in print about conflicts and lawsuits?Remember George Harrison and the infamous "My Sweet Lord". He payed big...but under no circumstances did he try to "steal" the Chiffons "He's So Fine".
I've never known a really creative artist who wouldn't be horrified, knowing they had accidentally lifted a complete melody line. Perhaps Carlos worked it out behind the scenes. I sure would!
