In 1971, Glass Harp released a follow up album, "Synergy". Again Keaggy's Christian faith surfaced in some of the lyrics. The guitarist notes, "That album was a real experience because I was able to sing 'The Answer', a song I wrote right after my conversion to Christ. And with...producers and an engineer that didn't care about Jesus, I was surprised that out of 15 songs, one of the ten that got on the album was 'The Answer'. I praise Jesus for that work, because it's just a simple song of testimony." The following year the band released its third album: "It Makes Me Glad", which included a version of the old spiritual "Do Lord". "We all worked the best that we could. The group knew that it would be our last album together because I had given notice that I was going to leave. And on August 8, I did. It was a really heavy thing for everybody."
