Dan has a great voice and there are times he's asked to appear with other artists on their albums.  Here's a few.

Tim Ryan's latest "Tried, True and Tested" is the class act of the group.  He and Dan perform a duet in the second verse of the last song "Say Goodbye To Montana".... awesome!  Good over all album, but then I do like Tim Ryan and always have.      Precious Child is the story of Christmas retold in the words by Thom Schuyler.  Dan is totally overshadowed by Vince Gill.  It's a nice Christmas album.

Dan sings back ground vocals for both Kix Brooks and Suzy Bogguss.
