You’ve seen the pictures, now check out the video of Grammy Award-winning rocker Melissa Etheridge joining the cast of Million Dollar Quartet for a legendary one-night-only jam session. The excited singer joined Jerry Lee Lewis (Levi Kreis), Elvis Presley (Eddie Clendening), Carl Perkins (Rob Britton Lyons) and Johnny Cash (Lance Guest) to add some of her signature grit to the classic tunes "Trouble" and "Ball & Chain". It may be just us but Melissa is looking pretty comfy on the Broadway stage!
