Looking for the following Gaither Homecoming videos:

A Homecoming Christmas
Landmark
Moments To Remember
Country Bluegrass Homecoming Vol. 1
Country Bluegrass Homecoming Vol. 2
Feelin' At Home
Sing Your Blues Away
All Day Singin' At The Dome

Lots to trade.

Gaither is aired on RFD TV every week. Have you tried looking on their schedule for the specific titles you are looking for?
I picked up some of the videotapes at a second hand store a couple years back, but I think they center around Gaither's Ireland stuff.
