I have been listening to old recordings of sing-alongs. It wasnt too low for me as a tenor. Today many people sing too low for me. I am thinking of music from older movies.
I actually like this key. It works well for tenors. It is not too low. It is often too low when I try to sing with people today. Did people sing higher before? And if so what was the reason for it?1 Answer
Perhaps I (and Cheddar) can be of assistance.
Essentially, this video covers how the invention of the microphone influenced the early 20th century music/recording industry and how it changed the music being produced, including the shift in popularity from tenors-only to more baritone/bass voices.
Namely, male singers had to sing higher to be recorded, but with the microphone, they didn't need to have high voices to be heard.

2There are probably other reasons, including popular taste, but this is a cool chunk of info. Commented May 16, 2019 at 13:11
