Question: American Spirit, an album released on American Gramaphone in 2003, is a collaboration between C. W. McCall and this group founded by whom?
Context: Christmas Song is Mannheim Steamroller's eighth Christmas album overall and the group's fifth Christmas studio album.  It was released in 2007 on CD by American Gramaphone, and features twelve Christmas songs.  It is notable that Steamroller co-founder Jackson Berkey doesn't appear on the album. The Legendary C. W. McCall is a greatest hits album released on audio cassette only by country musician C. W. McCall in 1991 (see 1991 in music), on the PolyGram label.  It does not contain any songs that cannot be found on the most well-known "best of" releases from McCall, "The Best of C. W. McCall" and "C. W. McCall's Greatest Hits".  Several errors were made in the track listing; for instance, "Black Bear Road" was listed as "Black Beer Road", while "Crispy Critters" was given the title "Crispy Critter". The Real McCall: An American Storyteller is an album by country musician C. W. McCall, released on American Gramaphone in 1990 (see 1990 in music) and rereleased in 1999 (see 1999 in music).  It features revamped digital versions of some of McCall's better known songs, including "Convoy", "Wolf Creek Pass" and "Black Bear Road", rerecorded by the artist for the album.  It contains more songs than any other release by the artist, with sixteen tracks in total.  It features songs from most of McCall's albums, the exceptions being his later works, "C. W. McCall & Co." and "Roses for Mama".  One new track, "Comin' Back for More", telling the story of the infamous American cannibal Alferd Packer, was recorded for the album and serves as its opener. Hourglass is the thirteenth original studio album by American folk rock duo America, released by American Gramaphone in 1994 (see 1994 in music).  This was America's first new studio album since 1984's "Perspective".  Two singles released from the album, "Young Moon" and "Hope", did get some airplay in the U.S. but neither charted.  The two songs did receive even more airplay in Europe.  The song "Hope" became a theme song for the TJ Martell Foundation and was recorded by a group of country music stars in a fundraising effort for the Foundation.  The recording of "You Can Do Magic" included here is not the hit version but a re-recording that is very similar. The Best of C. W. McCall is a greatest hits album released by country musician C. W. McCall on the PSM label in 1997 (see 1997 in music).  As with all "best of" releases from McCall, the album contains the wildly popular song "Convoy", as well as eleven others.  The cover is almost identical to that of McCall's second album, "Black Bear Road". Christmas Celebration is a compilation album by Mannheim Steamroller.  It is the group's seventh Christmas album overall.  The album was released in 2004 on CD and DVD by American Gramaphone to celebrate the 20th anniversary of the group's first Christmas album.  The album features eighteen Christmas songs in progressive rock and Renaissance styles, and includes three new tracks: "Celebration", a vocal version of the previously released "Traditions of Christmas", and "Messengers of Christmas", a Target version bonus track.  The remaining songs are new mixes of previously released songs.  A limited edition version of the album, available exclusively at Target stores, featured two extra songs: "The Holly and the Ivy" and "Messengers of Christmas". Mannheim Steamroller is an American Neoclassical new-age music group founded by Chip Davis, that is known primarily for its "Fresh Aire" series of albums, which blend classical music with elements of new age and rock, and for its modern recordings of Christmas music.  The group has sold 28 million albums in the U.S. alone. C. W. McCall & Co. is country musician C. W. McCall's sixth and last album of original songs, released on Polydor Records in 1979 (see 1979 in music), before McCall (or, more accurately, Bill Fries, the man playing his role) announced his retirement from the music industry.  Out of the ten tracks, only one ("The Little Things in Life") was written as a collaboration between McCall and Chip Davis, the man responsible for popularizing the distinctive McCall persona, while one other, "Silver Cloud Breakdown", was composed by Davis several years earlier and was featured in the movie "Convoy", though it was not present on its soundtrack. Christmas 25th Anniversary Collection is a compilation album by Mannheim Steamroller.  It is the group's eleventh Christmas album overall.  It was released in 2009 as a double CD by American Gramaphone, and features 25 Christmas songs.  It contains songs from their "Mannheim Steamroller Christmas" (1984), "A Fresh Aire Christmas" (1988), "Christmas in the Aire" (1995), "My Little Christmas Tree" (1997), "" (1998), "Christmas Extraordinaire" (2001), "Christmas Song" (2007) and "Christmasville" (2008). American Spirit is an album released on American Gramaphone in 2003 (see 2003 in music) as a collaboration between Mannheim Steamroller and country musician C. W. McCall.  The album focuses on American patriotic songs, hence the title.  McCall contributed to a number of spoken word songs on the album and rerecorded his 1976 hit song "Convoy" for it; this was also the case with another song of his, "Wolf Creek Pass," which can be found on the album.
