2nd hand guitar

I've been looking for a guitar in a charity shop for well over a year now and I've finally got one at a good price with a good sound. I've not played a guitar since I was 12 years old and i wasn't that good at it even then even though i was having guitar lesson - I was better playing the recorder!!!

Anyway, my challenge for this week is to play a song all the way through without my finger tips blistering :(
