old accoustic guitar. (Ditchingham NR35)

I'm just about to celebrate my eightieth birthday and want to play the guitar again, in a very rudimentary way, to accompagny nursery rhymes with my two glorious grandchildren . I had some lessons when I was sixteen- inspired, I suspect, by Joan Baez., and can just about remember the chords- also thanks to You Tube there must be someone showing elderly people with arthritis how to improve their playing!
