I've just seen this on the Leigh board, and only 64, apologies for the cut and paste:
Sad to hear this news. I loved him at Saints in the mid late 70's when my dad used to take me to Knowsley road to watch Saints before I discovered Leigh. As has been said he had a phenomenal side step for such a heavy guy, he also had great turn of pace over a short distance. I recall a cover tackle on the touich line on a breakaway he made at Knowsley road and couldn't quite figure who it was, only to discover it was him. I still don't know how he got there. For me he was on old style prop of the type we no longer see...short, very squat with large gut but bags of skill.
RIP
