"He was the happiest retired man I know," said his wife, Terri, who met him 41 years ago at a Variety Club telethon.
"Don was a legend among legends," Gerry Wilkinson of Broadcast Pioneers of Philadelphia wrote on the group's website. "When you thought of morning drive, you had to think of Don Cannon. He was one of the good people in this industry. I can't remember a time when someone asked Don to do something and he couldn't or didn't do it."
Mr. Cannon received a lifetime achievement award from the March of Dimes.
On WOGL's website, a statement mentioned the Rocky scene: "Don often joked that people missed his cameo because they were so grossed out by the drinking of the eggs that they were yelling during the scene and missed some of his announcing."
During his career, he also worked on-air at WIP-AM (610), WFIL-AM (560), WIFI-FM (92.5), and WSNI-FM (104.5). On the management side, he was a program director at WIFI, WSNI, and WPGR-AM (1540).
He also appeared on television as the host of Inside Golf on Comcast SportsNet.
In addition to his wife, Mr. Cannon is survived by sons Russell and Christopher, and three granddaughters.
A memorial service is scheduled for 2 p.m. Sunday, Aug. 24, at Joseph Levine & Sons Memorial Chapel, 4737 Street Rd., Trevose.
Memorial contributions may be made to the Heart Pavilion at Lankenau Medical Center via www.mainlinehealth.org/lmcgiving.
