Ritchie Blackmore - I wrote it on the spur of the moment. I had a very melancholy kind of tune. Then I started thinking about Jon. I thought maybe we should do an organ part at the end, as a tip of the hat to Jon. Pat Regan is an accomplished organist. We put the organ sound on, and off he went. I guided him on a few things, like riffs and how Jon played syncopation with his right hand.
