The Bugle tune at 12:08 is called various names by different BB Companies. Our band refers to it as Bombay. 2 other BB companies in our Battalion refer to it as Cavalry and the 5th Halifax Old Boys Band refer to it as Mandy. Liberty isn’t a name I have heard this being called. There is a tune out there called Liberty which was composed by Joe Winter back in the 1920s when he worked for Potters Of Aldershot, but that tune is in 6/8 time. Bombay/Cavalry/Mandy is in 2/4 time and is a lot shorter
