The Jonas Brothers keep going...and going...and going.

Fresh from the American Music Awards, where they were named Favorite Breakthrough Artist and performed "Tonight" (above),  the trio capped off the festivities with a free three-hour 24-song concert at the House of Blues on the Sunset Strip.

They decided to put together the gig at the last minute on Saturday, their rep tells me. After promoting it on the radio and their MySpace page, about 1,000 fans were already lined up several hours before Kevin, Joe and Nick even arrived.

And the fans got more than just the trio performing all of their hit songs.

Read on for all the details...

They covered John Mayer's "Gravity," Tom Petty's "Freefallin'" and Bob Marley's "Waiting in Vain."

They even covered their hip-hop hero Kanye West's "Heartless."

Then there were the surprise guests.

Their Camp Rock costar Demi Lovato jumped on stage to sing some of her singles with the brothers and also John Mayer's "Daughters." Jordin Sparks was a showstopper when she joined them for Stevie Wonder's "Superstition." Jesse McCartney was also a performer with his hit, "Leavin'."

The most interesting pairing? The JoBros and Dan Aykroyd covering the 1956 Bo Diddley hit "Who Do You Love?"

The show ended shortly after midnight with all the performers back on stage for the Beatles' "Hey Jude."
