Well, it's actually the 2nd movement of Jeno Hubay's violin concerto number 2, and arranged for band rather than one soloist. It is on my web site. The pdf score is free to print. There is audio too. Band parts, also in pdf format, are available free by special request to my email address. Who was Jeno Hubay? Hungarian violinist, composer, teacher. Born 1858; died 1937.
