Music for Brass - Paxton Records 7" PEP103 - Hungarian March by Berlioz, then Lohengrin by Wagner. 

This is side 2 of the Third of the series of Paxton, Music for Brass 7 inch EP's, released in the late 50s to mid 60s.
First track is Hungarian March by Berlioz, then Intro to Act III Lohengrin by Richard Wagner
Played by the All Star Brass Band, which was put together and conducted by Harry Mortimer.
These EPs are fairly rare now and quite collectable. I will add the whole PEP series in due course.
