The rDbb,bg5 chord could also be thought of as a wFgr chord
The most consonant voicing of a yb chord is with the b7 in the upper register. As a low-voiced male singer, that means I usually don't get to introduce a septimal note into a chord. But this song is different: the b7 is supplied by the bass voice moving up by a r2 and "tricking" the high voice into a b7. Great fun!
