As of June 2024, the group consists of Ernie Haase (tenor), Doug Anderson (baritone), Dustin Doyle (lead), Christopher Taylor (bass) and Tyler Vestal (piano).

In 1999, the Cathedral Quartet announced their farewell tour due to the ongoing health issues of George Younce and Glen Payne.

Following the tour Bennett and baritone Scott Fowler formed Legacy Five[1] while Ernie Haase continued his solo career.

[2] Subsequently, former Cathedrals bass George Younce and Jake Hess, along with Bill Gaither formed The Old Friends Quartet with Ernie Haase, Wesley Pritchard, and Garry Jones.

The Old Friends Quartet disbanded after about two years on the road, however, as Hess and Younce's ill health prevented them from doing much traveling.

Later Shane Dunlap left Signature Sound to start a solo career after release of their third album Glory to His Name in 2003.

Jones and Haase dissolved their business relationship after the first year and Roy Webb was chosen as pianist.

Due in part to the popularity of these concerts, the two groups decided to record a single album together, entitled Together, which debuted in October 2007.

In January 2009, Ernie Haase announced a Cathedrals tribute tour was next on the quartet's agenda and the group started touring with a live band that included Wayne Haun on the piano, David Griffith on the bass, Kelly Vaughan on electric guitar and Zak Shumate on the drums.

[6] In April 2015, Doug Anderson announced in a video with Haase that he will be stepping down from his position in Signature Sound to pursue a full-time solo career.

On September 11, they renamed it to Friday Night Sing, a 16 episodes series of stories and songs which featured many special guests.

In October 2021, they created a second season of the Friday Night Sing called Good To Be Home, a 10 episodes series.

Just like the first season, they shared stories and sang songs from their Keeping On album and it too feature some special guests.

On April 23, it was announced that Paul Harkey will step down from the group after 12 years at the end of May 2024 and that Christopher Taylor will be the new bass singer on June 15.
