To be fair thought this is the problem, I was going to chose a song that everyone knows a band for but they had three other minor hits after (one got to number 16, the other two in the 20's or 30's), no one remembers them but they were hits.
Like Nic I love those sites with all the facts, I too am disappointed that they don't seem to be updating everyhit.com at the mo, there's soem wonderful little facts on there as well, like today I learned that The Four Tops "Reach Out I'll Be There" was recorded in two takes & the band for about it and had discarded it at one point as "album filler", it went on to be their only number 1 hit.
