Mike Nes is wailing "The House Of The Rising Sun" (by Eric Burton/The Animals), with Peter Torken on keyboard, Josh Huskwolf on drums, Max Lennon on rhythm guitar and Paul McGear on bass guitar. On occasion they get together and do full concerts with their own respective tribute songs, and sometimes random songs from other bands.

Mike and Peter are from The Prairee Chikenz (aka. "The Prairees", a Monkees tribute band).
Paul, Josh and Max are from The Fab Gears (a Beatles tribute band).

"There is a house in New Orleans
They call the Rising Sun
And it's been the ruin of many a poor boy
And God I know I'm one

My mother was a tailor
She sewed my new bluejeans
My father was a gamblin' man
Down in New Orleans

Now the only thing a gambler needs
Is a suitcase and trunk
And the only time he's satisfied
Is when he's on a drunk"
