Great interpretation.....this was a keyboard song, top to bottom, Lukather wasn't even really playing anything, except the outro solo. If you do it on guitar, you have to create a rough approximation of interval chord shapes like you've done here. Another variation might be fashioning a combined melody line and chord arrangement on acoustic guitar.....that might work also. But, bottom line, you've captured most of the distinctive sounds, notes, bends in solo, really nice feel and emotion....a great song, no? Lukather was embarrassed to play this tune live for a while......think about that. Incredible.
