TheSingingMixer: #YoureAMeanOneMrGrinch is a deliciously dark tune about all that is against #Christmas! @funtastic crafted a gloriousy groovy #fullband #cover that was just too fun not to #collab! If you’re feeling the groove, too feel free to #joinmycollab! #MerryChristmas #HappyHolidays #Holiday #tsm #krm
