Here’s a look at the rehearsal for moe.‘s version of “Celebration” which the band performed on New Year’s eve in Boston. Al Schnier’s son is druming, while his daughter is on keys. Rob Derhak’s son is on trombone and his daughter is on vocals. Vin Amico’s two daughters contribute sax and sing as well (as does he).

Here’s how it came together on the night of the show.
