Margaritaville.com revealed this morning that video of Jimmy Buffett’s show tonight at the First Niagara Pavilion in Pittsburgh will stream live on Ustream.tv.

Several shows earlier in the year were broadcast live on Ustream, but recent shows have not been. You might check the Big Top Tour Ustream channel around 2 or 3 pm to see if they broadcast any of the sound check.

And as always you can listen to the show live on Radio Margaritaville on the web at RadioMargaritaville.com or on Sirius 31 / XM 55 beginning at 8 pm ET.

After two shows in Jersey, the 2010 Under The Big Top Tour continues tonight as Jimmy Buffett and the Coral Reefers perform at the First Niagara Pavilion in Pittsburgh, Pennsylvania.

You can listen to the show live on Radio Margaritaville on the web at RadioMargaritaville.com or on Sirius 31 / XM 55. Tune in shortly after 8 pm ET as Jimmy takes the stage.

After tonight, the tour rolls on to Chicago on Saturday. See all of the remaining tour dates here.

Jimmy Buffett and the Zac Brown Band collaborate on the single “Knee Deep” on the group’s upcoming album You Get What You Give, and Billboard details how they hooked up:

“We met him on a camping trip last year,” bassist John Driskell Hopkins reports, “and just sat around the fire with him for awhile. That was a quick friendship. He’s a real cat, really down to earth and doesn’t have a whole lot of ego and just a super nice guy…We did a lot of vocals down at his place in Key West and he happened to come through, so we got him to sit in and it sounded great. It sounds like a Buffett song when he sings it. Whatever he sings sounds like a Buffett song, y’know?”

Pre-order the album now at Amazon.com for $12.99.

The circus came to town Tuesday night as Jimmy and the Reefers played their second of two shows on the Under The Big Top Tour at the Susquehanna Bank Center in Camden, NJ.

Notable additions to the set list this time included “Frank and Lola,” “Wings”, and “Gypsies in the Palace,” last played in Sunrise in February. “Wildflowers” was tonight’s final encore, just the second live performance of this song ever.
