We all get by with a little help from our friends...even Stephen Colbert!

When Colbert made his debut as the new host of The Late Show on Tuesday night, he had the support of one of his famous friends: Jon Stewart!

The former show of The Daily Show and Colbert's longtime friend made a surprise cameo in Colbert's opening number, and it was pitch-perfect. Literally.

During his first-ever Late Show opening, Colbert sang "The Star-Spangled Banner" with random people throughout New York, taking over a bowling alley, too, before ending at a baseball field. And the umpire at said baseball field? Stewart!
