I haven't been to the RnRHoF in a couple of years, but I love the One Hit Wonders exhibit. I think that most of my record collection is made up of these one hit wonders.
When I was purchasing records, I always bought the followup 45RPM record to all the one hit wonders. A lot of you probably remember "Spirit in the Sky" by Norman Greenbaum, but how many of you have heard "Canned Ham"?
Or "Venus" by The Shocking Blue. The followup was "Mighty Joe".
I've got dozens of followup flops in my record collection.
