Mansion was a rock band based in Harrisburg PA and formed while I was in high school, in the mid 70's.
The lineup in the pictures was: John Mosser - drums, John Knox - guitar, Frank Leister - guitar, Robin Shenck - vocals, Mike Knox - bass.
This lineup ended in late 1975; however the band had a memorable two-day reunion in December 2000, twenty five years since we last played together.
The video and the music excerpts are from the Mansion Reunion in 2000. The pictures are from 1974, 1975, and 2000.
