In the late 1980s, I went to see 'Cats' at Blackpool, when it toured. Loved it so much I saw it three times that season. Brian Blessed played the boss cat, Old Deuteronomy. but anyone who has seen the musical knows that he only appears at rarer moments, even though it's a 'big' part. So, to get more time on stage (probably- him being a born show-off) and keep everyone happy during the interval, he would plonk himself on a huge tyre on the stage so people could go and chat to him/ get autographs (what we did pre-selfies). I didn't bother because he was always surrounded but thought it was pretty sweet of him. I like the guy. Some people find him a but much but the mould was broken when they made him.
Also remember him telling a story about how he befriended a wolf or something when he was on one of his expeditions. He described how they would howl together and kiss each other goodnight. Had me chuckling....dunno why that story stuck but it did.
