When I teach songs they are usually in the original key. If I change the key of a song for a lesson I'll talk about that right up front.
When you play the guitar for yourself or for someone else to sing it's best to fit the song to your voice otherwise someone is going to be embarrassed. 
If you're new to Rock Out Loud it's best to connect with an incognito Chrome browser and use headphones. The sound is better than on Zoom. I use it for online lessons all the time.

See you soon, Hal
