Guest - not by me, they haven't! I always appreciated their music.
One amazing thing about the group was when Bob Nolan retired, Tommy Doss's voice was so remarkably similar to Nolan's that a lot of people thought Bob Nolan was still with the group.
And Lloyd Perryman who did most of their arranging was brilliant.
BTW, in my not so humble opinion, Bob Nolan should have been a Singing Cowboy star, along with Roy, Gene, Rex Allen at al.
