Bing Crosby - Marijuana Advocate. Certainly explains that laid-back crooner song styling, dunnit?

Bing Crosby smoked pot:

"A 2001 biography of Crosby by Village Voice jazz critic Gary Giddins says that Louis Armstrong's influence on Crosby 'extended to his love of marijuana.' Bing smoked it during his early career when it was legal and 'surprised interviewers' in the 1960s and 70s by advocating its decriminalization, as did Armstrong."

And, of course, my favorite Bing song, appropriate to the holidays...
