I was on the Pollstar web site today and noticed that it lists an opening act for Buffett’s Great Woods shows in a few weeks. The band’s name is Mudhens. They are only listed as opening up for those two shows in Mansfield, MA.
Here is a link to the Mudhens listing on the Pollstar site: http://www.pollstar.com/tour/searchall.pl?By=Artist&Content=MUDHENR&Key=Y
Their web site confirms that they are playing the “Side Stage with Jimmy Buffett at 6:30pm”
