Tom Hanks was a final guest on Conan's last "Tonight Show," and if one trusty tweet is to be believed, Conan blew $500,000 on Hanks' walk-out song.

When Hanks entered from behind a curtain to go to his seat, the band played The Beatles "Lovely Rita," which costs NBC half a million dollars.

Questlove, who is the drummer for The Roots on "Late Night with Jimmy Fallon," almost instantly tweeted,

tom's walkon music on conan is on my "restricted" list---wow a $500,000 walkon song lol.

The song was in honor of Hanks' wife Rita Wilson.

Earlier this final week Conan played the very pricey "Satisfaction" by the Rolling Stones when Adam Sandler was on.
