I looked around at the news and message boards on his site and didn't see anything, but of course, sometimes things don't get posted to websites right away.It had all of his concert schedules up to date and all, so I hope whatever you heard is inaccurate.
Also, for anyone near NYC, I did come across this for Woody's birthday:
