When Ricky goes into the hotel, he goes to room 2112 which is Rush guitarist Alex Lifeson's room. "2112" was a hit for Rush in 1976 and was co-written by Lifeson.
Ricky mused that Alex Lifeson was like any other rock star when it came to saying he's down to Earth and approachable when he isn't. Actually Alex Lifeson is the most approachable of the three members of Rush.
