TheSingingMixer: If you do #acapella, you've got to #cover some #FrankieValli (& #TheFourSeasons are pretty essential, too)! Here's #December1963 #OhWhatANight with #Piano and #acapellaensemble. If you're inspired to take a shot at the solo, please #joinmycollab, & if you want to #drum, #guitar or #bass that's the bottom row from l-r -#replaceaway! Key of Db/C# I had a blast, hope you do, too! #tsm
