It was sad that brass bands weren't attracting young players any longer.
"And, of course, the rest of us are getting older and older. Youngsters are not interested in brass bands. They've got a lot more going on in their lives these days."
The Hawera band still played, but usually only at civic occasions, he said.
"I don't know what will happen in Hawera come the day when the brass band doesn't march through town. It will be terrible."
The band had an impressive history as a New Zealand A-grade band and champion in those early years, Mr Edmondston said.
The band was put on its feet and trained up by Harry Fox, acclaimed New Zealand jazzman Rodger Fox's grandfather.
"It has a remarkable history with the talented Fox family."
Born and bred in Hawera , Mr Edmondston said he even surprised himself that he had never moved away.
"And I'm still living in the family home."
Band chairwoman Christine Cameron is keen to find as many past members as she can for the reunion. Even though she sent out dozens of invitations to previous players, she realises not everyone will attend.
"Well, not everyone is still interested."
The Hawera Brass Band was formed in June, 1878, with 12 instrumentalists and a big drummer, she said. But today there were just 10 players.
Mr Edmondston said: "Well, sometimes there are 12 of us."
Even though it was a struggle for the band he said he was convinced it wouldn't fold.
"I don't think so. We're an institution, you see, and a very strong one at that."
