its nice to know there must be a delorian mode, harpgirl. i must tell this joke to my band members someday when we are annoyed about the mode. mode problems sometimes occured when we play bluesy tune. 7th or major 7th, and major 3rd or minor 3rd. it's often confortable for us to play 2nd, 3rd, 6th code against root code as major code with 7th for old jazz tunes. like this: C/C/C/A7/ D7/G7/C/C. of cource Am7 and Dm7 can applied but we think major code is more sofisticated mood. so i usually use root mixolydian scale for bass line on every bluesy tune but some other note from code will be added adequately.-takeo
