If I see the title I can usually remember the song - found a list recently from 20 odd years ago and was shocked by how many I haven't sung in years but pleased to realise I could remember a lot of them. DT took a hammering as I checked on others.I find tunes more of a problem - my active repertire of Morris tunes is down to 10 from 50 in the days I played regularly - time to start a new notebook!
All the best
Steve
