Nice job on the collaboration....my 2 cents is IMO this song is screaming for an underlying B3 slow leslie......
then let it rip on the chorus at 3:55 to end.  
  I agree....Actually I went there before the strings, but I was afraid I would do a cheesy organ part as I don't play organ....And I would get called out on it....LOL...So I went with the strings which I knew I could pull off
I'll revisit it for sure, cause that is what I heard too
