there in 2010. Organ When the Alabama was built in 1927, films were silent and required a musical accompaniment. This was typically provided by an orchestra or theater pipe organ. The Alabama's organ is a Crawford Special-Publix One Mighty Wurlitzer. Only seventeen examples of this model were built, and the Alabama's is one of only three still installed at their original sites. Nicknamed Big Bertha, the Alabama's organ is a four-manual (keyboard) organ. It was originally installed with 20 ranks (sets of pipes), but has been expanded to 32. It also features numerous percussion instruments and sound effects to accompany silent movies.
