Meanwhile, Elijah mentioned Dom in a recent interview:

I brought down like 4 Case Logics full of CD's because I was there for so long. We DJ'd a couple of parties and Dom (Monaghan) and I DJ'd together and we'd played at bars and I was just playing songs. ... Now I'm doing it more frequently and being asked to DJ.

Elijah's SDCC panel on his US cable show Wilfred will be later on Thursday.
