Arty Facts with Master J is a show about working in the arts. Today: Master J is joined by West End theatre performer Karen Holmes. With the recent announcement that the 64th Grammy Awards have been indefinitely postponed, Arty Facts has decided to help out by listening to, reacting to, and then deciding the winner of the 2022 Grammy Song of the Year. Songs critiqued and scored include: Ed Sheeran’s Bad Habits, A Beautiful Noise by Alicia Keys and Brandi Carlile, Olivia Rodrigo’s Drivers License, and Fight for You by H.E.R. This is the first in a three-part series, at the conclusion of which the winner will be crowned, and Karen Holmes, having heard the song once, will attempt to sing it. For more information visit Master J on Facebook. [Repeats Thursday 3.30am.]
