Thank you, I'm glad you found value in my version. It's not from a tab, I picked it off the cd but I'm not a uke player and had to convert it to the upper 4 strings of my guitar. But it's a backing track for a string instrument so the chords don't have to be voiced exact. Just a reply to your pet peeve on the use or over use of triangled 7th chords. Their use, most of the time, will slightly change the voicing of the chord and in addition will alter the bass and drums, like adding a syncopation or a roll or change the bass line. So for me, the variation more imitates a live player and makes for more interest so I don't get bored hearing the same 4 chords over and over when I play against it. If you want to hear another of my versions where I made really heavy use of these chord variations to relieve boredom, pull up my George Benson version of Breezin'. There's a ton of triangle chords,as well as 6ths and 9ths as variations off the main 4 chords just to add a bit of interest in a real basic and repetitive chord cycle.
THANKS for your interest in my Rainbow version!!! much appreciated.
