When Frank Avruch retired as WCVB-TV’s Bozo the Clown in the early 1970s, Worcester Channel 27 picked up the franchise. But who would be the new Bozo? Tom Matzell was the station’s jack-of-all-trades at the time, alternately working as a camera/lighting man, production director, or even weekend anchor if need be. Seems he fit Bozo’s size 64½ shoes just right. When Matzell rolled into the Convention Center with his Bozo costume, fans came running from everywhere. His appraisal was also a hit.
