The good news about Boston hosting its July Fourth festivities on the 3d is that locals won’t have to miss Tom Bergeron hosting “A Capitol Fourth” for PBS on Friday. It’s a bit weird for Bergeron — a Haverhill native — to compete against the WBZ-TV-televised Boston Pops Independence Day celebration that was to take place at the Hatch Shell on Friday night. “Now you can watch two in a row,” Bergeron told us Thursday in between rehearsals for his July Fourth gig. Bergeron, host of “Dancing With the Stars,” said he’s received a few tweets from fans who’ve asked why he isn’t involved with Boston’s celebration. “My answer is: They didn’t ask.” Bergeron explained that he’s not the only local who’s in D.C. instead of on the Esplanade. Boston Pops Laureate Conductor John Williams is one of the “Capitol Fourth” performers this year. “I shouldn’t be getting all the grief,” Bergeron joked. “A Capitol Fourth” will air live on WGBH 2. The lineup also features Frankie Valli, Michael McDonald, Phillip Phillips, and Patti LaBelle.Names can be reached at firstname.lastname@example.org. Follow Mark Shanahan on Twitter @MarkAShanahan.
