Shores of the Mighty Pacific - Concert Band Accompaniment

[druby]

Back in 1968, when I was in high school, I played Herbert L. Clarke's "From the Shores of the Mighty Pacific" with concert band accompaniment. The publisher was M. Witmark. I would like to play this again on the occasion of the 40th anniversary of that event. Unfortunatly, I have been unable to find the band parts as they seem to be out of print. Does anyone know where I might find the band accompaniment to this wonderful old gem?
