"Sweet Caroline" is played during every Red Sox game at Fenway Park. So I'm sure it gets airplay in Boston.I would venture to say there’s probably a second 60’s song that still tests well and is heard on some classic hits stations and that is Neil Diamond’s 1969 hit Sweet Caroline. I don’t have the data in front of me to back that up but I know it’s still played at weddings and parties and the crowd dances and sings along to every word (sometimes even inserting an extra 3-word phrase that wasn’t part of the original lyrics).
Back in July, I tracked the playlist of WCBS-FM for a few days, and they only played two '60s songs: the Beatles' "Twist and Shout" (1964, but re-released in 1986 after being featured in "Ferris Bueller's Day Off"), and Steppenwolf's "Born to Be Wild" (1968).
