Live Nation is expected to announce Thursday that Billy Joel will play at Fenway Park June 26. The Piano Man hasn’t released a new pop album in over 20 years, but he does seem intent on touring. Joel, who’ll turn 65 in May, recently kicked off a series of monthly concerts at New York’s Madison Square Garden, and already has shows scheduled next summer at ballparks in Chicago, Washington, D.C., and Philadelphia.Mark Shanahan can be reached at email@example.com.
