I call The Flying Newspaper "a companion" to my weekly sing-a-longs. It's a newsletter but only sort of. I do put info about upcoming shows and other projects I have going on in there but I'll also throw in historical tidbits, stories I've heard, quotations, jokes, lyrics and chords, background on songs, pictures to color, and other stuff I find interesting.
There are two versions of this week's companion. One is the general edition and features a guitar to color. The other is a special Williamsburg edition that explains the (small) price increase at my Knitting Factory sing-a-longs this fall.
Come to one of my sing-a-longs and I'll give you a copy made out of real paper.
