Who's That Guy Paul McCartney? Some Kanye West Fans Apparently Have No Idea

— -- Kanye West's emotionally charged new single, “Only,” is dedicated to his late mother and 18-month-old daughter. It's become an instant hit, with a little help from another musical genius, Paul McCartney, on keyboards.

Based on their tweets, it appears that some of West’s younger fans don’t’ know who the Beatles legend is.

It’s not clear whether the posters were trolling, but the tweets understandably drew a swift response.

But there was some understanding for the apparent ignorance of youth.
