This doesn't always apply, but one of my main tricks is knowing what guitar "cowboy" chords look like. This is a real advantage having come from guitar. I can see if its a G or D, Am, etc. If it's a barre chord, I can usually see where that's at also.
That's my non-auditory answer.
As far as listening is concerned, finding the beat, etc. Knowing "standard" progressions can help a lot. But with classic rock, particularly Beatles, that doesn't mean much.
It really is IME standard and normal for the rhythm guitar to blurt out the main chord progression in a jam.
It's also fairly expected to not play songs with a lot of chromatic changes that are pretty much impossible to jam to.
I think you will find that, even after a short time, you probably already know "E", "A" "D", "G", probably C and F also, by heart, stone cold. If not, you are probably very close.
Even if you don't know the shapes, when a guitar player strums a standard G chord, it really announces itself.
