'Who Will Host Tonight?': Jimmy Fallon and Jay Leno Duet About the Future of 'The Tonight Show'

The last time NBC tried to change the host of The Tonight Show, Jay Leno and Conan O'Brien found themselves in a bitter feud over the future of the late-night institution. While the specifics haven't been ironed out yet, it looks like that won't happen to Leno and Jimmy Fallon as NBC once again tries to send Leno into retirement.

The cold open of Monday night's Late Night with Jimmy Fallon featured Fallon and Leno "singing" a duet about their current situation, borrowing heavily from West Side Story's Tonight. Fallon closed the sketch by thanking Leno, making it clear that the Late Night host planned on keeping things as friendly as possibly.
