Tully was an Australian progressive rock band active from the late 60s to the 70s. They gained prominence as the backing band for the June 1969 Australian production of the musical HAIR. Tully was noted for their musical breadth, as members of the band were all highly accomplished multi-instrumentalists who were not only polished in their sound, but adventurous as well. They were reportedly the first Australian band to use the Moog synthesizer, although their sound evolved in later years from their organ-dominated sound to more gentle melodies, many with spiritual significance.
