Are composers David Haas and Marty Haugen as popular in non-Catholic worship as they are in Catholic worship?

Whoa, whoa, whoa! Haugen wrote The Song of Mark?! I love that! I was in that! I totally didn't know he wrote it.

Anyway, I'm a Catholic and I very much appreciate Haas and Haugen. Although I do know some more traditional Catholics who would rather stick to Gregorian chants, these two composers are certainly here to stay. You'll find them in any Catholic hymnal, and they form sort of a common web of knowledge among Catholics. You mention Eye Has Not Seen or Blest Are They, for example, and practically any church-going Catholic can sing along.

From my experience, however, this is not the same with Protestants. They must have their own composers because they seem unfamiliar with Haas and Haugen. I remember in particular a couple of times when some of my musically-inclined Protestant friends and I exchanged religious hymns. I was very surprised to discover how many songs I thought were universal, but that they had never heard of. Canticle of the Sun was one of those. If nowhere else, however, their songs have to be used in the Lutheran Church, since two of Haugen's best known liturgies (Holden Evening Prayer and Now the Feast and Celebration) were specifically written for Lutherans.

No, I never heard of them but then again I never really pay attention to who actually wrote the song we are singing in service.

What song did they compose? It would remember the title more than the composer I think.
