Acoustic rock songs for a group of three guitarists?

Im looking for some acoustic rock songs for 16-17 year olds. Songs we have learnt before include stranger things have happened - Foo Fighters, hallelujah - ??, other bands like nickelback, foo fighters, red hot chilli peppers, a little bit of green day, jack johnson and some bon jovi. Now im looking for sum popular, mainstream songs that can be performed on the acoustic guitar. Any suggestions would be awesome so feel free to write down your favourite tune as long as it sounds good and possibly falls into my category!?!? Thnx
