I remember it well. It was Michael Elphick's finest hour, in my opinion.
Here's a bit of pop trivia for you....The theme song, "Hi Ho Silver" was recorded by the late Jim Diamond. He had a hit with the song, but he had also previously had a Top 5 hit with "I Won't Let You Down", as lead singer with PhD in 1982. He was also known for his 1984 No.1 "I Should've Known Better".
One of the best from the Quo, in my opinion. It also has one of the best guitar intros of any rock song from the 1970s, in my opinion as well. You can't beat a bit of Quo!
