LZ III degrees of separation Saw his "Band of Joy" on late night TV doing one song a couple weeks ago, think it was NBC. Is that Patty Griffin backing up RP in BofJ? Patty (or Patti?) was on "Austin City Limits" maybe three weeks ago, a week before John Paul Jones' and David Grohl's "Them Crooked Vultures" was also on A.C.L. (Supposed to have full episodes at pbs.org). Vultures was pretty cool, JPJ played any number of odd bass instruments with Grohl on drums. The lead singer/guitar and a dual-lead guitarist were good, though I'd never seen them.
