A few of them I don't remember at all, and there are a bunch that I do remember but haven't heard since 1971. Many of them were hits but rarely (or never) got played on Oldies stations, back when they were Oldies stations, that is.
And then there's the song at #2, "Timothy" by the Buoys. Great song. Huge around here. Strangely, it was also popular in Western Kentucky, where I jocked for a year in 1974-75. We used to play it as an Oldie all the time on 570 WKYX. And that's not the Blue Grass State's coal mining region either. I don't remember if the original version of the song was played or the version with the lyrical change. It's interesting how regional hits were common back then.
Speaking of the Buoys, I think Rupert Holmes of "Pina Colada Song" fame wrote that song or was a member of the group, or both.
