It hasn't been well publicized on the 'net, but it looks like Hootie & the Blowfish are going to be performing a free show at SubFest this year at Submarine Base New London! The July 4 show is listed on the Hootie web site here, and in the Subase MWR newsletter here.
For those lucky enough to be in the Groton area (now there's a phrase you don't hear everyday) you won't want to miss out on the show. My family and I saw them at the Orange County Fair back in 2004 (free tickets from the MWR in San Diego) and it was one of the best concerts we've ever seen. In the much more intimate setting they have at Subase, it should be really good.
I'm assuming the base will be open to civilians again like it was last year. For those who missed it, check out the comments to my post about last year's SubFest to relive the "Resolved: It's a pain in the ass to have all the townies tromping around on the base" debate.
