There was a term I first read years ago in an interview with Johnny Carson in regards to taking all the crap in show business called FU money. He said you reach a point where you have enough money to tell the show biz powers that be just that. I think Anka long ago reached that stage. He wrote the Tonight Show theme while Carson was on and got a royalty check for each one. Anka was a teen idol in the 1950s and has had a very very long and lucrative career.
“He wrote the Tonight Show theme”
Wow! I didn’t know that. My oldies station plays a medley of his songs. He’s a great music man!
