Anything could be possible, but the easiest way to find fast your nearest shops who do out music instrument renting, that would would be the best and cheapest solution.

This is not about do You learn that You need or don't - some chords on paper. I think there is nothing wrong with that when You have an 3 hour gig or first time rehearsal with a pro band. I always use those notes about songs to be better even if i know the song allready completly. This guy who came empty could easaly hear those 4 songs and write down the chords and some nuances and it would be OK. But he didn't spent an hour and choose to drink a lot of bear and watch some soccer match.
