Remus Lupin
When Remus stepped up to sing, he signaled for the music to wait a moment.
"Mr. Moony would like to dedicate the follow song to Misters Wormtail, Padfoot, and Prongs--Prongs doubly so, since he isn't present--who didn't get to hear this song when it came out. Here's to the days when we felt like we were princes of the universe." With that, he signaled for the music to start.
