was really shocked saw ecchan played more than 2 instruments. I hope in that formation their sounds not to be changed (yeah, althought it must be changed). i think they've to get an additional player for drum, cause maybe it'll be so hard for them to plays and changing instruments in (maybe) every song they played. i worried that'll influencing their performance. IMHO, just my oppinion
but, most of it. i really salute to them on that performance. keep moving on Chatto!
