I realise this is of no interest, but John Grace, one of The Boatmen, was were Junior School teacher when I was 10 (1974-75). I still have a copy of Straight From The Tunnel's Mouth. I remember how naughty it felt then to sing things like "now I'm a bugger for tea" (from The Single Bolinder).

He was a great teacher, warm and inspirational. I have no idea where he is now.
