Actually Bob Zentz will be in Waltham at 2:00.
Put on by the Folk Song Society of Greater Boston (you might have to scroll down).
You'll have to contact the Song Society to make reservations & get the address & directions from the Are they trying to not make this easy?)
It's $10 & $12, I'm not sure about the price differences, maybe 1 price for members & the other price for non members?

Directions & reservations email; suzanne@smrozak.com

For those of you who don't know Bob see him at his web site linked above, he's very interesting & a super entertainer.
