The Tony-nominated musical Million Dollar Quartet hit up Late Show last night for a visit with David Letterman. “If it’s not great, I’m gonna eat my tie!” Letterman proclaimed when introducing the cast. Luckily, there was no accessory munching required. The uber-talented Million Dollar cast performed rousing renditions of the show’s greatest hits, including Johnny Cash’s “Folsom Prison Blues”, Carl Perkins’ “Who Do You Love?” and Jerry Lee Lewis’ “Whole Lotta Shakin’ Goin’ On.” Want to be rocked? Watch it!
