Six Degrees of It's a Small World

Geo has a co-worker who is a Recorded Sound Processing Technician. RSPT has a boyfriend. Boyfriend plays in a band. The band played at a wedding reception in Dallas, TX, on May 15.

Yes, that wedding reception.

RSPT attended the reception with aforementioned Boyfriend. (She's also a musician, so she might well have played/sung with the band, too.)

RSPT had never heard of the groom before and had no idea who he is.
