Yeah thanks Mick - it really was excellent and goes to show, at least to me, that yoghurt isn't an essential ingredient in a tikka marinade. I only had time to marinade for about 4 hours, so a full overnight marination (is that a word?) would have been even better. The meal I made was Chicken Tikka Madras (using both Chewy's base and madras recipe and your tikka marinade).
