Russ Abbot songs

I have been searching for a particular sketch done by Russ Abbot, but i am not sure which show it was on or when,

basically it is the sketch about a London transport worker singing all the stations on the underground to a familiar tune,

if you know what season, which show or even have a link to the episode i would be Really grateful,

I dimly remember one where he kept ageing dramatically between verses.
