I'm usually playing a concert or soprano. Does that might make a difference?
I have progressed where I can make the Fmaj7 (2413) in the first position pretty well. That's a Twister game on the fretboard. I make the fourth fret on the C string with my pinkie finger.
I'm playing a concert this morning, myself. I can form that Fmaj7 (with difficulty), but the pinkie move you're making on the Beatles song is not going to happen....
