エキトピア祭開催中

I went to Sasashima to see Nakanomori band, Takako Matsu and so on. That's was brodcasted in FMA Pradise beat. Nakanomori band played two songs in it. According to their fan, their performance wasn't good today. I was given their secret live ticket. I'll go there if my schedule is all right. After we left Sasahima we went to the CD shop to look for CD "Ore ore sagi no donata." Unfortunately we couldn't find it. When we were in Gyokuondo, the members of Nakanomori band also came to the shop and introduced themselves. Should I have bought their CD and ask for the autograph?
