I knew it was Edgbaston. I was playing cricket* that afternoon - it was only a short time after test cricket was played on a Sunday.
I remembered the Edgbaston and the 5 and the 11. It was 5 for 1 run in 11 deliveries.
*FAGVO. A teaching colleague of mine was a pretty decent cricketer and had a match at one of the Bardfields, on the Dun Run route. They were a player short so he gave me a lift there in his MGb. The ground was surrounded on 3 sides by a cornfield. The other side was back gardens. I batted at no 11 and scored 1 not out, didn't get a bowl, and fielded mostly a long way from the bat. Nevertheless, I took 3 catches! One was at mid-off. The ball was driven straight at me at about head height. Technically not a hard catch for a good cricketer (I'm not), the ball stung my hands a lot. The other two were skiers on the boundary. The second was memorable because another fielder came running for the catch (it was coming straight to me) and he knocked the ball and diverted it into the crook of my left elbow, from where I held it aloft. I think we must have won the match.
