OMG JANKENPYON GLOVES I say a big YES to shin mini moni doing old mini moni song revivals. Oh I hope that's on the next concert DVD *crosses fingers*
Plus all the other revival groups doing old songs: Hell to the yes! I miss those Elder Club and Wonderful Hearts concerts where they would just let different people sing Shuffle group songs or Tanpopo/Pucchi Moni/T&C Bomber/Biyuuden/Otome-Sakuragumi/etc...
