Ernie is best known as the 10 year tenor of the Cathedral Quartet, but he has also sung with Squire Parsons & Redeemed, The Dixie Melody Boys and others. After the Cathedrals retirement, he started a group called Old Friends Quartet, where he sang part time with Jake Hess, George Younce, Wesley Pritchard, and Garry Jones. Due to George & Jake's health, many of those concerts were done with Mike Allen filling in for George, and Wayne Pritchard filling in for Jake. Ernie started getting the quartet bug, and formed Ernie Haase & Signature Sound with Garry Jones in late .
