I did Kenpo Karate in the Daigokan hall in Killester.
Late 70's, up to Brown belt.
3 times during the week, and Sunday morning.
Alas, I discovered a Lass and never went back.
Brendan was the Instructor.
Derek Doody, best black belt I ever fought.
Dave Roberts equally so.
At the time there was Kenpo, Taekwondo, Shotokan, and Wado Ryu.
Now there's all sorts.
