The family nickname of comedy writer Chevy Chase who came to national attention during 1975-76 season of NBC’S SATURDAY NIGHT LIVE as a bumbling, pratfaller who stumbled at the beginning of each show and shouted “Live from New York…It’s Saturday Night!”
Soon after Cornelius Crane Chase was born on October 8, 1943, his paternal grandmother began calling him “Chevy” when he was a kid in New York.
The name may have been derived from a possible reference to the Washington, DC suburb or to the English ballad which tells the perennial story of the Scottish border feud between the Percys and the Douglases.
No one knows however, not even Chevy. But whatever the reason, the name stuck and became his professional showbiz non de plume.
