Former British Prime Minister Margaret Thatcher died Monday (April 8) at the age of 87, and the Oak Ridge Boys have issued a statement in remembrance of the fallen leader, whose indomitable will earned her the nickname "Iron Lady."

Thatcher served as Prime Minister from 1979-1990, and she headed up Britain's Conservative Party from 1975-1990. The stong-willed leader was as much a conservative icon in England as her American counterpart Ronald Reagan was in the US, and through working hand-in-hand with him on many policy initiatives, she became a favorite of American conservatives as well. It was through that link that she met the Oaks, who are longstanding supporters of the Republican party.

"The Oak Ridge Boys were in attendance when Baroness Margaret Thatcher gave her last public speech. We there at the invitation of then President George W. Bush," singer Joe Bonsall says in a press release. "As I recall, it was a dinner honoring Ronald Reagan and we sang several songs that evening and got to spend a bit of quality time with Lady Thatcher. It was a great  honor and a very memorable event for all of us."
