Bob waxed (and whined) at length about the  history of one of his favorite Christmas songs, “Have Yourself A Merry Little Christmas,” as he does almost every year. This year, however, the convoluted lyrical evolution of the song was particularly relevant given that most of us had to content ourselves with the melancholy little holidays that the song invokes. But it was not all gloom. There was the usual helping of Detroit Junior, Lil Ed, and Canned Heat to provide a bluesy flavor, along with Ronnie Fauss, John Prine and others to make you miss down home. And happy 80th Birthday to Jorma Kaukonen of Jefferson Airplane and Hot Tuna fame.
