Baby Shower Pandora Stations?

So this has nothing to do with my pregnancy per se, but my bff is also pregnant and is 5 weeks ahead of me. I'm throwing her a baby shower soon, and I'm thinking that some background music might be nice, especially at the beginning when people are trickling in and beginning to mingle, but I'm sort of stumped. The theme of the shower is Paddington Bear, as she loves the books and movie, and fell in love with London, where she travels frequently for work. It's not a super formal shower, just a mid morning party with heavy brunchy snacks, tea, punch, and it will be hosted at my home, so maybe classical music would seem too stuffy? Any suggestions on appropriate background stations to play through Pandora? Thanks in advance! Y'all are the best!
