Query: KISS, Don't Let Me Down Next Time!!

I have been kiss fan for 16 years. I want to say is this DVD really let me down! It's only 4 songs. The bonus are not surprising either. This DVD is not authorized by KISS. We hope the real full length make-up concerts DVD will published as soon as possible. DON'T LET ME DOWN AGAIN, KISS!!
