The Birthday Song needs more COWBELL

In a 2019 interview with Jimmy Fallen, Will Farrell says that he went backstage after seeing Christopher Walken in a play and Walken said Farrell had ruined his life. Ever since that infamous SNL sketch, Walken says people yell "more cowbell" everywhere...even we he takes a curtain call in the theater!

Happy Birthday to man who has the need...the need for more COBELL. Walken turns 78 years old today!
