In 2007, SBC purchased eight copies of Rise Up Singing for group gatherings. Technically, they belong to the folkdance club, and over the summers they live in the folkdance club lockers in LPAC. Email the Folkdance folks (Katherine Bertaut or Ames Bielenberg as of 2011) to get them.
There is a Folksing mailinglist, folksing .at. sccs
.dot. swarthmore .edu. , which you can subscribe to at this
sccs page. It is very low traffic, about three messages per
semester, generally whenever someone decides there should be a
sing. Anyone subscribed to the list can send mail to it, and
anyone is welcome to schedule or announce a sing.
