It's closer than you probably think it is. Grand Funk Railroad sold 25 million albums while Creedence sold 26 million. GFR had 7 top ten albums, two #1 singles, but never a #1 album. Creedence had 5 top ten albums, zero #1 singles, and two #1 albums. I'd call it a draw on album sales and popularity. But for some reason Creedence made the Hall in 1993 and GFR continues to be snubbed. GFR deserves to be in the Hall a lot more than some who are already in, especially the non-rock (e.g. Hip Hop) acts.
