He has been making music for over 50 years and has worked with some of the biggest names in the business, so it's no surprise that Barry Gibb has some tales from the world of music.
The Bee Gees star has recorded a new album with the help of his sons, and he caught up with Good Morning Britain to discuss the latest record, but first he gave his opinion on the greatest ever artist.
Barry counted Michael Jackson among his closest friends and the two would often hangout together in the studio making music and giving each other advice.
However, Barry claims that despite all of Michael's success as one of the biggest selling musicians of all time, he was incredibly insecure and had some severe self esteem issues.
Barry said: "I've never known an incredibly famous artist that had good self esteem. Michael was the same, very much afraid, afraid of everything."
He added: "He'd say to me, 'Barry, do you think Prince is better than me?' I'd tell him he had no equal."
Barry thinks that fame made the Thriller singer insecure, and that's something he has seen in many other stars in both film and music.
"Mega-fame is destructive", he said. "My wife is the reason I didn't wind up going down that path."
