Who says Governor Charlie Baker is all business? Baker dropped by Johnny D’s the other night to catch the Stompers, the East Boston party band fronted by Sal Baglio. (You might recall their 1978 single “Coast to Coast.”) Afterward, Baker tweeted a selfie with Baglio, bass player Steve Gilligan, and keyboardist Jeremy Brown. “Had the pleasure of watching Sal Baglio & The Stompers tonight at Johnny D’s. 30 years later, they still got it!,” he tweeted.Names can be reached at firstname.lastname@example.org.
