I love knowing the background and history behind songs and tunes.  Lyle Lofgren’s and Bob Waltz’s little essays cover mostly songs but some show up in our sessions, like Angeline the Baker,

Lofgren is no longer with us, but he was one of those big-hearted, big-brained nuts that got this whole old time music revival going.  Lots of interesting stuff, musical and otherwise, is archived on his website.
