A self-described “refined and elegant environment” usually reserved for power lunches and partisan hobnobbing, the Capitol Hill Club is rolling out the red carpet for heavily tattooed, über-capitalist crooners Madison Rising tonight.

The vehemently conservative band, which was blocked from serenading Occupy Wall Streeters up in Zuccotti Park last fall, won’t be denied again.

They’ve already signed up to perform at the open mic stage (6:15 p.m.) arranged by Occupy Congress protesters — who’ll be speechifying on the West Front Lawn of the Capitol all day today. The capstone to MR’s visit, however, should be the free show — during which they are expected to perform such anthemic compositions as the left-bashing “Honk if You Want Peace” and pro-military “American Dream”— hosted by the CHC.

A CHC aide confirmed they don’t usually book musical acts (“unless it’s a wedding”) but said a club member vouched for the band. “We have members at the CHC that are our friends and love us and asked us to play,” an MR spokesperson said of the wildly irregular booking.

No word on which track the band might play during any encores. But given the venue, may we suggest sending everyone home with the closing verse of “In the Days that Reagan Ruled” still ringing in their ears:

“Tearing down an iron wall,
Acting in his greatest role,
Made all his critics look like fools,
’Cause even jellybeans were cool!”
