I think it needs done. I cannot be the only one who's noticed the quiff has been on a slow demise? In all of the recent footage we've seen of him (the One show it was especially flat and styled differently), Jimmy Kimmel, etc, there hasn't been too much there in terms of quiffage.
I'm okay with it, I actually wish it would've gone out though in it's better days. It hasn't been looking as good in awhile.
While it may be "time", you, the fabulous quiff, will be remembered fondly.
