On this week's episode, the guys offer their take on the greatest hits of Rainbow, featuring Ritchie Blackmore, one of the biggest influences on heavy metal guitarists in history. Ritchie's riff on "Smoke on the Water" made so many young kids pick up an electric guitar and try their hand at that riff.  But this week, Kenneth Dean and Chris each choose their 15 favorite Rainbow songs.  Whichever is duplicated, make the list.  The rest are debated to see which ones make the final 15.  Then they put the songs in concert setlist order for the ultimate Rainbow Greatest Hits.  And they also offer their BIG 4 Rainbow Alumni Songs at the end.  The qualifications to make the list was that the song had to be written by or performed by a former member of Rainbow.  So sit back, relax, turn it up to 11 and let the debate begin.
