Billy has been out and about performing the theme tune to the new Pokemon film at two US premieres for the movie. First up, an enthusiastic crowd outside the world famous Mann's Chinese theatre in Hollywood, California, got to see him strutt his stuff, before he went on to join other celebs such as Rob Lowe, Kirstie Alley and Christine Lahti for the southern premiere of the movie. Billy then headed up to New York where he joined up with M2M for the movie's East Coast premiere on Nov. 9 at the giant Warner Bros store in midtown Manhattan. Shuttled in on the Pikachu-mobile, Billy spent time signing autographs, chatting with fans and discussing the nuances of the phenomenon that is Pokemon.
