The most consonant voicing of a h7 chord is with the z7 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 z7 is supplied by the bass voice moving up by a r2 and "tricking" the high voice into being a z7. Great fun!
