Glad you liked it, I checked the Website and there is no Pokemon Theme songs which made me quite sad because there are some nice tunes from Pokemon and SSBB made me realise that. The versions on the actual games are relatively crumby but can sound great if arranged properly.
Oh well also there aren't going to be any Concerts performed in the UK in the Near Future. You may have seen but they also do quite a few other themes such as World of Warcraft, they also did an arrangement of One By Metallica and played it with the Guitar Hero 3 Version in the Back Ground. They Didn't match it to the Visual though.
