SOMERVILLE, MA – Somerville Mayor Joe Curtatone and Boston Mayor Marty Walsh released a joint video Wednesday celebrating Somerville's 175th anniversary. Set to pop hits "Hello" and "We Are Never Ever Getting Back Together," the mayors satirized the two cities' "break-up," and indicated that the split – though amicable – is permanent.

"We shared a lot of great memories with our old friend Charlestown," Curtatone said. "Like that late night, moonlit horseback ride with our friend Paul Revere. And we can still remember our very first phone call from the phone on Lincoln Street, with the number one. Oh the memories."

But Somerville has moved on – "we've grown," Curtatone quipped, and declared the city "Charlestown's cooler sibling."
