Well I've been a grandad for five weeks. Our lovely but non-stop-yelling grandson lives over two hundred miles away from us, in Richmond (the London one), unfortunately. We were there today though, and, as I proudly pushed him around the rainy streets (no-one else was getting a go) and Thames-side paths, I found myself singing (a word I use advisedly in my case) this song to him. It worked, I swear it! My mum used to sing it to me and I "sang" it to mine, and I'm determined that this family tradition shall live on. Well, at least as long as I can persuade my son from singing Johnny Cash songs to the little lad ALL the time! I'm pretty sure my mum got it from the singing of the wonderful Paul Robeson.
