Feltbeats recently asked Tom Felton some questions on behalf of SS and Matt was mentioned.
FB: And doesn’t Matt Lewis play? [guitar]
TF: And Matt Lewis, yeah! I didn’t realize he jammed on the strings! He sent me a message the other day. He said, “Loved the new song; I really want the chords.” And I didn’t realize he played the guitar. That’s cool, that’s cool. We’ve got another jammer on the list.
