I'm sure someone can tell me, who was the Black Watch Pipe Major in 1970?

I met him at a performance here in The States, and was majorly embarrassed when he called the band to attention upon my introduction, but despite that had an interesting conversation with him and some of the band members. For the life of me I can't remember his name. He autographed the program for me, but it was destroyed when the roof spring a big leak during a major storm. I'd like to know his name again.
