The other day I heard "The Rain the Park and Other Things" by the Cowsills - another amazing sunshine pop song.
Sirius radio should dedicate a station to it, like they have one for Yacht Rock.
It could be a good pop-up channel or on the app. Lots of sunshine rock on 60’s Gold - Spanky and Our Gang, Association, Ms and PS, etc plus some regional favs like the New Colony Six that was huge in Chicago.
