Chords-wise, there is no difference between this version of Welcome to Paradise and the more polished version that was later recorded for Dookie (the version we still hear blaring on the radio today). The primary difference between this version and the Dookie version of Welcome to Paradise is that this version is a tad bit faster, the guitars aren’t tuned perfectly to Eb, and the guitars themselves are much thinner sounding than the beefed up Dookie version. However, this version is the original, therefore making it a classic!
