The BPP crew's been getting to work at about 4 a.m. since going on the air, and we aren't shy about expressing our crankiness before we've had our coffee. But today, musician Ben Harper dropped by and put us all to shame. Ben was on Letterman last night and hadn't slept since, although you couldn't tell from his performance at BPP HQ.

This is Ben playing "Fool for a Lonesome Train" from his new album, Lifeline. Tune into the BPP tomorrow morning for his interview with Luke and Alison and his performance of "Fight Outta You." We'll post the audio of the entire interview here tomorrow.
