I think most have agreed that he did sing once
If he shaved, he may begin to:
sing properly
think about composing music more
learn a new technique to overuse
and take his foot off the damn wah

Agreed. Much as I like his stuff, the last few BLS albums have been a case of 'enough of the damn wah pedal and picking every note, already!'
BTW, that's coming from someone who posesses a Zakk Wylde Dunlop Wah - I just don't use it
all the time. I also have a legato lead style, which helps!
