Neil Diamond songs are great for this, and also 'The Beatles', they will also be a great learning template for Rythm and Timing, Plus John and Paul wrote almost all their songs on acoustic guitar first, so they are well apt. If you have an Ipod, or IPad etc, there is a great ap you can download for about £5.99 , 'The Beatles Little Black Song Book' it has every Beatles song with chords, backing tracks and some learning Video's, it's great! if you don't have an iPod it is available in plain book form from most Guitar shops or over the internet . Good luck to you.
