NBC's Saturday Night Live continues to thrill with its line-up in March running the gamut from Emmy winners, to Super Bowl MVPs and U.K. rock stars and an award winning American Idol. On March 17, "SNL" alum and actress Julia Louis-Dreyfus returns to Studio 8H and to the show where she got her start and where she made a triumphant return last season. Louis-Dreyfus, an "SNL" cast member from 1982-1985, is the first female alum to host the show.

Joining Louis-Dreyfus on the show is British trio, Snow Patrol. The band, which features a fusion of a variety of alternative song styles, will perform from their hit record "Eyes Open."

On March 24, SNL welcomes Indianapolis Colts quarterback and Super Bowl XLI MVP Peyton Manning to host. Since joining the Colts as the number one overall draft pick in 1998, Manning has rewritten the record books earning two NFL MVP Awards and making five Pro Bowl appearances prior to his stunning Super Bowl victory earlier this year.

Joining Manning on March 24 is musical guest and American Idol winner Carrie Underwood. Since winning "Idol" in May 2005, Underwood's debut album "Some Hearts" has sold over 5 million copies and has produced four No. 1 singles.
