If you have been to the forums at gonnahitcharide.com, you probably know of komit, who is a reliable source of information when it comes to Boston. Komit has made a very interesting post. The info was also posted on Boston_Rocks.
...Rumor has it that a concert in honor of Brad is scheduled for August 19th, in Massachusetts. It will include numerous bands, ending with Boston's last live performance, which will include all members that ever played with Boston, including the 3 other original members. Barry's bands RTZ and Ernie and the Automatics will perform as well.
There is also talk in that post that this show will take place in Mansfield, MA at the Tweeter Center. Also, it is said that Brad's kids were planning a show with the other bands and that Tom was planning a show as well, so it was decided that the two would be combined.
