This is a rip off of Station Man

[bretonbanquet]

When they first started playing "Station Man" live in 1970, it was much slower, and it gradually sped up during 1970. They stopped playing it sometime in 1971, and it was only when it got revived by the '75 line-up that it sounded anything like "Gudbuy T'Jane". Even then, I think it's only a vague resemblance - the Slade song was always much faster Slade always did their own thing, and I doubt they'd have been listening to "Kiln House" at that time, to be honest.
