Black Joe Lewis & The Honeybears stopped by The Late Show with David Letterman on Monday night to perform “Livin’ In The Jungle” from their recently released third album Scandalous. The Austin blues ensemble, dressed like “Jehovah’s Witnesses,” according to Letterman, turned out a performance so groovy, it easily could have been taped in the late 1970′s. Fresh off his weekend at Bonnaroo, frontman Joe Lewis jammed on a red guitar, matching his rose-accented leather suit, while the horn section completed the retro set. It may have been hard to tell what Lewis was singing at moments, but that did little to hinder the vintage vibes and rhythm-soaked soul of the performance. The song was so high energy, even Letterman asked to “have that every night.” If only you could let them, Dave.
