DENVER -- Maryland Gov. Martin O'Malley informed the Arizona delegates to the Democratic National Convention of a hidden talent Gov. Janet Napolitano possesses - she can play a mean tambourine.

O'Malley, Napolitano and a couple of other state executives had a jam session at the DNC gubernatorial caucus Wednesday night. The line-up included Virginia Gov. Tim Kaine on harmonica and O'Malley on guitar. Montana Gov. Brian Schweitzer filled the room's prescription for cowbell, and rounding out the rhythm section was Arizona's own Napolitano.

"She wasn't rolling her eyes [while playing] - she put herself into it. Did a good job," said O'Malley of his ersatz band's tambourinist. Overall, O'Malley gave the group decent marks.

"Like the Patridge Family, but over the hill," was how he characterized them. "We had a good ol' time."

A little ways into the set, the Rev. Jesse Jackson took to the stage too, which was what pushed the moment into the surreal for O'Malley.

"I woke up in the morning," he recalled, "and said, 'Was that a dream?'"
