Any info would be appreciated

Hello, George.

Nobody has answered yet, so here is at least a partial one.

The music begins with the opening melody of 'Alpenlieder Marsch' - 'Alpine Songs March', by L. Gruber. The following sections are different. It's likely that L. Gruber used several songs as inspiration for his march.

The organ performance could also be a medley, of course, so we probably need someone who has a good Alpine song repertoire.

Apologies for it not being much of an answer; my library is impractically large to search for unknown tunes. If the march turns up soon, then you'll have a better reply.

Let's hope that this response triggers somebody's memory.

Regards,

Richard.
