My Welsh is a bit rusty so forgive a bit of Saesneg talk.
Can anyone here tell me about a hymn I loved when I was a kid in school in Wales. The chorus was " Dring Dring Dring" or " Climb Climb Climb".
I've googled it and asked many people without success , but I'm sure I didn't imagine it and it seems that this is a place where someone might know the proper title so I can hear it again.

Diolch.
