Identify this British song

I am looking for a song where I only have a vivid recollection of the video.
They were performing at the BBC’s Top of the Pops.
There was one guy singing kind of monotonous with a drumcomputer.
He was wearing an old military uniform and in the background there was a line of people with old-fashioned instruments, tuba, drum and things.
There was something in the lyrics about drums and there was a line “rom-pom-pom-pom” repeated in every chorus a few times.
Anybody any idea?

Educated guess: Jona Lewie - Stop The Cavalry

Jona Lewie - Stop the Cavalry?

Yes, that is the one I looked for.
Thanks you guys, you rock.
