An uncle of mine used to sing a song which went

Charlie Brown walked down the aisle
Bumpity Bump Bumpity Bump
The bride she walked in with a smile
Bumpity Bump Bumpity Bump
And the bridesmaid Eva Dunn, had a dot and carry one
and the parson strange to tell had a Bumpity Bump as well

The usual thing. I cant get any further. can anyone help with Lyrics and /or history.
Martin. ex cockney.
