According to their Facebook page, The Brady Bunch star Barry Williams will be making several appearances at this year's Yarmouth Clam Festival.

The actor, best known for playing the part of Greg Brady, will be the marshal for the parade on Friday, July 19th, and he'll be signing autographs on Saturday, July 20th.

Williams, and the rest of the Brady kids, have been pretty busy lately.  Since HGTV purchased the old Brady Bunch home, they've been helping with the renovations.

Entertainment Tonight recently stopped by to see how the renovations were going.

Get more details about the show at HGTV's website and don't miss Barry Williams in Yarmouth this summer.
