Part of the reaction to the deaths this week, and this year, has been people of a certain age (including us!) realizing that we're old. Yes, George Michael and Carrie Fisher died far too young, but they came into our consciousness what is now a long time ago.
The Empire Strikes Back (whose first seeing by this blogger at a cinema in Berkshire is still vividly remembered) came out in 1980. Take a look at this partial list of Top of the Pops performances in 1980. If you're of that vintage of ToTP watcher, the list probably includes some characters and preferences that you haven't thought about in a while.
