Blues Brothers.
The deejay had some blow-up microphones, guitars, and saxophones, so a bunch of us did a lip-sync of I'm a Soul Man. Rather than post several pictures, I just made a collage. From left to right in the top middle picture are my brother Todd on air-guitar, my aunt's boyfriend Keith on air-sax, my sister's boyfriend/escort Matt also on air-sax, me and cousin Jim on air-mics, and my mom's boyfriend Alan also on air-guitar. Hopefully you can tell where they are in the other pictures as well.
