The two musicians were among hundreds of tuba players who came to the Kennedy Center to play in the concert, which originated in 1974 as a tribute to the late artist-teacher William J. Bell, who was born on Christmas Day in 1902. Participants were asked to wear bright colors. They rehearsed for two hours before performing onstage at 6 p.m. (Barbara L.
