I disagree on music with many brothers and sisters in Christ that I do evangelistic work with, I don't shun people over music, Now I will never be a part of their music, but I don't believe I cannot work with them to fulfill the Great Commission.
Here's a snippet about Gaither from

Bill Gaither has had an ecumenical philosophy from the beginning of his musical career. In his autobiography It’s More Than the Music, he states that one of the fringe benefits of playing their concerts in “neutral, nonchurch environments” was that people from “all church denominations” attended.
“Before long, Baptists, Methodists, Presbyterians, charismatics, Catholics, and Pentecostals were all praising the Lord together. Subtly, the walls between denominations began to crumble...” (Gaither, It’s More Than the Music, p. 115).
“Hymns for the Family of God” was purposefully “nondenominational” and included devotional readings from a wide variety of Christians, including heretics such as Deitrich Bonhoeffer (one of the fathers of Neo-orthodoxy), Malcolm Muggeridge (a liberal Roman Catholic who did not believe in Christ’s virgin birth or bodily resurrection), and Robert Schuller (who has wickedly redefined the gospel in terms of his humanistic self-esteem theology).
The Gaithers provided the music one evening at Indianapolis ‘90, a large ecumenical charismatic gathering that I attended with media credentials. One-half of the 25,000 participants were Roman Catholics. A Catholic mass was held each morning conference, and Catholic priest Tom Forrest from Rome brought the closing message. Roughly 40 denominations were present. The Gaithers were perfectly at home in this unscriptural gathering and entertained the mixed multitude with their jazzy music.
The Gaither Vocal Band performed at the Promise Keepers’ second major men’s conference in Boulder, Colorado, in 1994. Promise Keepers is radically ecumenical. In an interview with the Catholic publication Our Sunday Visitor, Promise Keepers founder Bill McCartney said that full Catholic participation was his intention from the start. “Back in 1992, at our first stadium event, we very clearly stated from the podium that we eagerly welcomed the participation of Roman Catholics, and we’ve had scores of Roman Catholics attend and go back to their churches excited” (Our Sunday Visitor, July 20, 1997, p. 10). The Tidings, a Roman Catholic paper, stated that Promise Keepers included Catholic congregations (March 31, 1995). Catholics were encouraged to participate in Promise Keepers because “there is no doctrinal issue which should cause concern to the Catholic Church” and “there is no attempt at proselytizing or drawing men away from their [Catholic] faith to another church.” Catholic priest John Salazar spoke at a Promise Keepers meeting in Plainview, Texas, in December 1995 (Lubbock Avalanche-Journal, December 3, 1995). The Promise Keepers field representative for the upper Midwest at that time, Steve Jenkins, was a Roman Catholic. A Promise Keepers Wake Up Call brochure distributed in San Louis Obispo, California, urged pastors, churches and their men to attend special rallies during March 1996, one of which was held at the St. Rose Catholic Church in Paso Robles. In 1997 Promise Keepers appointed a Roman Catholic, Mike Timmis, to its Board of Directors. One of the speakers at several of 1997 PK rallies was Roman Catholic “evangelist” Jim Berlucchi (“Making New Catholic Men?” Our Sunday Visitor, July 20, 1997, p. 10). In June 1997, Promise Keepers hosted a Catholic Summit at its headquarters in Denver, “sounding out Catholic volunteers and leaders from around the world” (Ibid.). Promise Keepers organized a Roman Catholic mass as part of its Rich Stadium conference in Buffalo, New York (The Humanist, Sept. 19, 1997). Following a luncheon with Bill McCartney in January 1998, Roman Catholic Archbishop Charles Chaput of Denver gave a “thumbs-up” to Catholic men who wanted to participate in Promise Keepers (The Catholic Register, quoted in Religious News Service, Jan. 19, 1998).
