Today’s Family and Children’s Concert presented by the Tufts Department of Music is a special occasion: It celebrates the release of “Life’s A Song. Sing It Loudly!,” a digital EP of original songs by “Rainbow Jeff” Rawitsch! “Listen to Lincoln” Gray and “Musical Megan” McCormick join “Rainbow Jeff” for a concert to celebrate the achievement, which was two decades in the making, and remind all of us that “Life’s A Song. Sing It Loudly!” Rawitsch, the manager of the Granoff Music Center at Tufts who holds two degrees from the university, is a celebrated children’s singer-songwriter known for his trademark colorful outfits, including rainbow pants and tie-dyed shirts and sport coat.
