Go to Songtrellis working musician type chords, as well(realbook is great, but has a relatively small number of things) also check Ralph Patt's Vanilla Chord Book, which gets down to the basic, unornimented, simple turn-around stuff that you can build on(or not, depending on tastes)--OFMB at songtrellis is still a bit fancy for what Uncle Dave wants, though--

Hal Leonard, and music publishers in general, have someone paste in chords as an afterthought, usually based vaguely on what's written in the piano score--the chord fingerings are just random-
