TheSingingMixer: I’ve had #ANightingaleSangInBerkeleySquare stuck in my head for the last week, so I did what any #acamaniac would do, I recorded an excerpt to see if anyone would join me! Let’s call it a #ManhattanTransferChallenge - start a #cover and see if a few fine #acafolk will jump in to #collab & #harmonize! 8 open squares & a world of awesome harmony awaits! #Joinmycollab! #tsm #manhattantransfer
