they're not doing Rod Stewart.. they're doing American Songbook

the bald fella did damned well with a slow version of Wonderful
World... even Simon liked it... frankly, this song, requires
someone who does songs some other way in order to make it work..
especially those whose songs are not the soft ballad-types... the
contrast is almost required in order that the impact is
felt..
just like a rock or a bebop musician, slows down, looks at the
world, and is moved to sing this song...
frankly, a crooner or a sappy and irritating singer like say, Pri..
uhh.. Rick Price would have turned it into unadulterated
crap...
