DULUTH, MN (KDAL) - The fourth annual "More Cowbell" competition is being held Thursday night at Grandma's Sports Garden in Canal Park.  It's a benefit for the Northern Lights Foundation and begins at 5 p-m.  The competition is based on a "Saturday Night Live" sketch that featured Will Ferrell and Christopher Walken as a producer who pleaded for "more cowbell" in a song that was being recorded. Several celebrity contestants will be trying to out cowbell each other.  The event also includes a silent auction and live music.  The Northern Lights Foundation grants wishes and distributes funds to northland children with life threatening medical conditions and their families.
