It all started 27 years ago with a dozen people at Bar Thom’s on Grand River in Detroit. Over the years, it has been at many bars, and the traveling celebration has even spawned imitators. But there can only be one Babe Ruth Birthday Party, the one started by Navin Field Grounds Crew honcho Tom Derry back in 1988. The Corktown sports bar will be taken over by fans of the Sultan of Swat, who would be turning the almost impossibly old age of 120 that night. And with facts, stories, and images of the Bambino festooned all over Nemo’s, you’ll never have seen so many “Babes” in one bar.
