Well.... I performed "Free & Easy", "UNITE!" and "End roll" on manga/anime convents... well I wasn't scared but.... I'M NOT SINGING WELL but I LIKE TO DO IT

but it was OK.
Etto... in my school I once sang M and Trauma but it was a'capella and I tried to learn all the people the Trauma dance, but they didn't want to learn (boring people!)
Well... on some of our pack of friends meetings we have karaoke ocasually and I sang "ourselves" once and I'm going to perform "forgiveness" soon. Can't wait for the karaoke version of "no way to say" now...
Ah! Please notice that these performances weren't done for an ENORMOUS public. The convent ones were for 50 people, school ones for 60-100 people I think... it's not a crowd but it was fun
