Over the weekend, Bruno Mars joined a impressive roster of musicians asked to host Saturday Night Live, including Justin Timberlake, Mick Jagger, Paul Simon and Taylor Swift. Mars proved to be a good sport and up for anything as a host, including dressing in drag and singing as a number of other artists in a skit about Pandora.

In the "Pandora" skit, Mars played an intern at the Internet radio company, who had to step in and sing as other musicians when the company's computer servers went down. Mars showed off his impressions of Billie Joe Armstrong, Steven Tyler, Michael Jackson and others during the skit.

Mars also performed his new single, the Police-esque "Locked Out Of Heaven," as well as a new ballad, "Young Girls." Both songs appear on his upcoming album, Unorthodox Jukebox, due out December 11.

Tom Hanks also made an appearance on SNL in two skits, as well as introducing Mars' first performance. SNL also had its best ratings thus far in the 2012-2013 season, with a 5.4 rating and 14 share.
