Drum and bugle corps from across the United States, Canada, the United Kingdom and South Africa depend on Paul Collins’ business. He founded the Brass Shop in 1991, a mobile repair unit serving drum and bugle corps and marching bands at rehearsal fields and stadiums, taking care of the day to day problems encountered and not easily dealt with because of the logistics of the activity. The Brass Shop grew quickly to become a major repair service used by corps and bands across the continent as well as a Dynasty Brass, Marching Brass and percussion dealer and distributor for Silver Fox sticks and mallets. He played baritone or contra bass for three different groups between 1960 and 1984: the Rochester Crusaders, the Syracuse Brigadiers and the Sidney Royal Aires parade corps. He has also served on the board of directors of the Crusaders.
