Music title and artist?

[DeaPea]

I remember a single in the mid 70's, I think it was a b-side. The lyric mainly consisted of grunts and groans but finished with something like 'that the last time I ride my bike up that hill!'
I worked in a hotel at the time and the DJ always played it to get a reaction - I'm now trying to trace it for of all things a training programme.
Hope someone can help with a name and or title.

I'm sure it was on the back of a novelty hit - possibly one of Chris Hill's "Santa" singles?
