This was one of the first albums Billy Connolly released and it brought him to the attention of a much wider section of the British public. I recall seeing him on tour shortly afterwards and it was about the same time as he made his first appearance on "Parkinson".
Billy Connolly has become known as one of the greatest comics around, with a keen talent for spotting the absurd in everything around him. There are a number of great tracks on the album and they generally focus on the things that he knew then, i.e. Glasgow and Scotland.
"Harry Campbell & the Heavies"is a fantastic pastiche of Glasgow life, but so does the rest of the album, in fairness. The track that brought most notoriety at the time was "Crucifixion", a retelling of the last days of "The Big Yin" in Galilee. It doesn't seem to get much atention nowadays, but it led to irate "Christians" protesting outside all of his concerts for quite a while.
Don't listen to it if you're a Christian fundamentalist and/or you don't like sweary words. Otherwise, it's a fantastic laugh. BTW his accent was much stronger in those days, subtitles might be needed for some.
