Many are the childrens songs I described in the earlier thread, some remind me of singing them at school, others I heard since on the radio but they are often far more uplifting than much conventional music. I also like all the jazzed up Morris dances mainly made popular by Ashley Hutchings and Mike Oldfield. Technically not songs as instrumental but have the same effect.
We got an incredibly comprehensive collection, and although it probably belongs in the confessions thread I did also buy a couple of CDs of them. Who needs memories, why not just listen to them again properly? original thread
If you can add any more, please let me know. I may have forgotten a few.
