When our son was at nursery around 2005/2006, it was written in his report that as he was playing, he’d sing the Radio 2 jingle. Number 4 in this list. Brings back good memories.
The ones from 1998 and 2010 are classics. The latest one from 2023 is atrocious and characterless. It's nice to refresh a jingle every so often but it's difficult to imagine what they were thinking with this one.
