Matthew Morrison is pulling out the big guns for his upcoming solo album.
Elton says, "I just did it! It's a duet. It's great, really fantastic. He sings great on it. It's a medley of Mona Lisas and Madhatters going into Rocket Man. I did it on Monday."
Maybe this will lead into Elton doing a guest spot on Glee??!?
