[IMGCAP(1)]While Capitol Hill has long played host to numerous celebrities, not everyone gets to wield the Speaker’s gavel. In this 1965 photograph, Speaker John McCormack (D-Mass.) demonstrates to Liberace, the piano showman who was wildly popular from the 1940s through the 1980s, how to use the gavel. On his left is Democratic Rep. Clement Zablocki of Wisconsin, who represented Liberace’s home district.
