App song - Hometown Girl

Just looking at this song as a possible attempt to play. If someone else can check my thoughts here.

I curious about the Em change on an “&” strum, the D chord is fine though. !

I thought typically you play strings 1-3 for an up strum so do you up strum 4-6 or could you simply down strum because tempo is quite slow at 79 even though it would feel a little off to the tempo.

1 & 2 & 3 & 4 &

D Em
C D
