Okay, here's the address:

Bethlehem Lutheran Church
52nd and Central Avenues
Indianapolis

You might want to look at the society's website:

Whether you would call it "a traditional folksong club" is a matter of interpretation. Most members play instruments, but there is unaccompanied singing on occasion. Much but not all of the music is what I would call traditional.

The format of the meetings is as follows:

The first hour is what we call "show time". Only members of the organization may perform in this section. It's performance from a platform, with P.A. system.

The second hour of the session is jamming, in a large group. Sometimes there are also, in other rooms, workshops on various instruments or music genres.

The third hour is called "Sharing Circle". Everybody sitting in a circle, and each person (or small group) present has the opportunity to do something he/she/they may have on tap.

If you want more details you can ask me either here in the thread or by PMing me (DaveO).
