A ready-to-rock Joe Walsh took the stage last night at Jimmy Kimmel Live to kick out an old classic, the James Gang's "Funk 49." (The sequel, "Funk 50," appears on Walsh's latest solo effort, Analog Man, which you can listen to here). The Eagles guitarist held nothing back, whipping out a handful of rock-star power moves, a few throaty wails and heaps of hot guitar licks.
