If you recall from last Summer's Come Together tribute show, Michael Sweet shared the stage with Boston. Now according to a recent interview on Metal Rules, it looks like Michael will be much more involved with the band.
 

According to the interview, which was posted on Metal-Rules, Tom Scholz has asked Michael to record and tour with Boston.

From the article:
"...I got an email from a guy who runs a Boston fan site and he asked me if I wanted to comment on his death. I did and he posted it and Tom Schultz read it and contacted me and asked me to play a benefit show. From there it went from me singing one song to me singing three songs and playing guitar for the whole set. Now he’s asked me to record with them and tour with them. So I am facing the fact that they are not Christians but they have been a better example of Christianity to me than even some Christians. No drugs, no drinking, polite as can be and very giving. Their music and lyrics are clean. I prayed about it and I felt like it was okay for me to do it and I did it."
