I don't think those that old are still around. Analog AM radio listeners, however, are. For a long while I would say my radio games outnumbered my television games. (and still greatly outnumber my "in-person" games)
I grew up in Brockville in Eastern Ontario in the 70s. For many years, we got about one Leaf game every two weeks n TV. Both tge Kingston and Ottawa CBC stations carried the national CBC game which pretty much alternated between Toronto and Montreal. Up until 1975, we'd also get some Leafs games on CTV who used to have a Wednesday night package.
Radio was bad too. Before 1978, the only Leafs radio games we could get reliably were a handful of Sunday night games on CBC Radio. Part if the reason was that CKFH who did the Leafs radio games was at 1430 AM and the local Brockville station (with its transmitter just a mile or so from our house) was at 1450 AM which blocked any chance of picking up the Toronto station. We were able to pick up some games on radio from their home broadcasters (as far way as St. Louis). In 1978, the Leafs moved to the CKO Radio News Network which had an Ottawa affiliate, so we could finally get all the Leafs games reliably on radio.
As for remembering days when you had to go live, there's probably no one around. There might be a few who remember no TV, HNIC TV broadcasts began 72 years years ago, so someone woukd likely need to be at least 82 to remember those days. And I'm certain there anre some on these boards who remember HNIC broadcasts joining the games already in progress. Games used to begin at 8 pm but the broadcast wouldn't begin until 9. In 1964, the broadcast syart was moved to 8:30, and in 1968, they started broadcasting the whole game.
