The last two were legends of RL calling, Frank used to work alone on the sideline. No sideline eye, no-one but him. Rex had Barry Ross who was as exciting as watching paint dry. Gasnier was in a similar vein on the ABC with Warren Boland, he might have been the prince of centres, but he wasn't the prince of RL sidekicks. Don't remember Summons or Barnes as commentators, maybe before my time (although I remember Barnes as a player). I remember Ron (Won) Casey though, started as a league comm and went to radio with some success, as did Hadley.
Another radio caller I have fond memories of is Frank Ley, who called Panthers games on 2KA for many many years. We may have been a tinpot club but every match we played was on the radio called by Ley, and Paul Ambrisoli before him. Frank was as biased as thay come, but got away with it because his audience was exclusively Panther fans. The 2KA (Katoomba) signal barely reached Mt Druitt.
They all did their job. Gasnier was with Alan Marks and John O'Reilly as an expert comments man. He was also on the radio. Summons only did the one season in 1983 with nine. Barnes was on the Mid Week Cup broadcast and was very insightful. Hyde was mainly on sports programs and wthe radio which he is best known for.
I've been going through my old games so these are fresh in my mind.
