So the song they've rehearsed in Stavanger should be Back To Tupelo -- it fits with the picture, Mike plays guitar on it, capo is on the second fret and there's the F-Chord played in the chorus when playing with the capo.
Most likely,
Back to Tupelo is in the key of Bm existing of the :Bm,A,G,G6 &D chords.
so with a capo on the second fret you can play the :Am,G,G(6)barre 3rdpos. &C chords
On the picture you can see Mike playing the G-barre (E-shape) in 3rd position.
And he uses the same guitar during "Back to Tupelo" as the guitar on the picture
"so with a capo on the second fret you can play the :Am,G,G(6)barre 3rdpos. &C chords"
I'd rather say : Am, G, F, F(6) and C chords if you are in the "virtual" key of C.
And the F chord is played in the E shape, if you want, but to me, it's the way to play a F chord, if you imagine the capo being the end of the neck.
and, BTW, there a lot more chords on Tupelo than the few quoted here
