REALITY: Back in 1976, Blue Öyster Cult recorded “(Don’t Fear) The Reaper.”
According to former bassist Joe Bouchard, the ‘cowbell part’ was overdubbed by his brother Albert after the song had been recorded.
PARODY: In 2005, a skit on Saturday Night Live had guest Chistopher Walken pushing for “More cowbell” from Will Ferrell. No link due to copyright issues. We’ll let you Google that classic.
VIRTUAL REALITY: Finally in 2009, you can upload any MP3 song, and add your own cowbell courtesy of www.morecowbell.dj
What a wonderful world, wide web.
