Can someone please tell me what the song is playing on a Radio 2 trailer for Chris Evans' show?

It's at 1h 27 mins and 58 secs. It's a very familiar jingly song but Shazam and Soundhound haven't helped.

Here you go
Recognized it from the Crabbie's advert

You're a star, thank you!

On another song, would anyone happen to know where I can get a recording (not vinyl) of Remember Romance by Des O'Connor?
