Sounds like a nice time, maltrab. Wow, I just realised (via Google) that he played Chunky Livesey in the second series of First of the Summer Wine. Gonna have to re-watch those.
I liked the Crusher character. Sadly, his character did not get fleshed out very well before he left the show.
I can see Crusher, Tom and Smiler helping Auntie Wainwright with odd jobs. Could have been some good story plots with that trio. Felt Ivy a bit too harsh on him at times. I don't really see Crusher and Barry hanging out too often as friends. Crusher seemed a bit enthusiastic to have joined the force and been grouped with Cooper and Walsh. Possibly could see Crusher becoming one of Billy's Merry Men and helping on some adventures with Alvin and Entwhistle.
Seems my wishful thinking and daydreaming misplaced how early Crusher was in the timeline of things. Way before the other characters I mentioned above appeared.
