Most of the others have already said what I'm about to say, but I'd like to ask if you really want to hear "Honey" by Bobby Goldsboro? Do you know anyone who wants to hear it? It hit #1 in 1968 and stayed there for roughly a month, but the people I know who were around when it was a hit don't like it. Most of them say they didn't like it when it was new either. Enough people, of course, liked it at the time to keep it at #1 for several weeks, but they don't like it today.
Something else to keep in mind is that having a #1 hit doesn't mean your song is popular or that you're going to endure as an act. Approximately 1 in 7 artists who hit #1 never have another hit, and they're not always flash in the pan acts either. Sammy Davis, Jr. hit #1 with "Candy Man" in 1972. He never hit the charts again, and you never heard much of "Candy Man" either after it worked its way back down.
