Ask anyone to belt out their favorite Tom Jones song and you'll probably get "It's Not Unusual" -- arguably one of the most famous songs of all time.
Ask Mel Gibson to sing a few bars of his favorite Tom tune -- and you get a different famous song from an entirely different Jones.
Our photog spotted Mel leaving The Troubador last night, just moments after Jones himself was seen exiting the club, so the question was a no brainer.
There's plenty of Tom magic to choose from: "It's Not Unusual", "She's a Lady", "Sex Bomb" ... all were major hits.
But Mel -- always keeping it interesting -- chose none of those. Instead he chose (and sang) a song made famous by the legendary George Jones (although Tom was known to sing it as well).
