Theater buffs celebrated the 90th anniversary of the Tivoli Theater's organ with a melodic reunion.

The organ was installed in in 1924. The Wurlitzer Pipe Organ hit popularity in the 1920s when it was used to play music in theaters for silent films.

Saturday night, The American Theater Organ Society and Chattanooga Music Club celebrated that anniversary by screening the 1925 silent film, "Phantom of the Opera."

"The theater pipe organ was built to accompany silent films, and it was built to be like an orchestra, so there are voices like strings and clarinets and flutes and trumpets, but there are real xylophones, real glockenspiels, real tambourines and castanets and drums that play through the keyboards," says Ron Double with the American Theater Organ Society.

Organizers say events like this generate interest in the Wurlitzer Pipe Organ which are costly to keep up. The group is asking for donations to preserve the organ.
