you could try play along with the strumming pattern and chords that these guys are having fun with here:
YouTube- clips including Seven Island Suite jam (for 7IS, jump to the 4 minute mark if you wish)
it looks like the vamp section is basically Em A, with the capo up a few frets
Fmaj7 may be easier than the non-barred version of F but not sure if the vibe of a maj7 chord will suite (pun?
) the latter section...have fun regardless...the fine folks who were on the radio show last eve are the ones who could give you the best tips, just thought you might dig the video clip if hadn't seen that particular jam
cheers
