I've been saying all along that if some musical legends had had to audition on a reality TV show, they never would have had careers. Sure, 20 year old Elvis Presley would impress judges be they Voice, Idol, Xfactor, or Rock Star: Supernova.

But what about Mick Jagger? Would he get a ticket to Hollywood? Would Usher and Adam fight over the vocal talents of Tom Waits? Or Lou Reed?

Watch this really clever video to see what it might have been like if John Lennon had been born 40 years later and went to audition for The Voice. Also, stay tuned for the hilarious cameo at the end...
