Hymn Lyrics Search - Name That Hymn

Hi, I know this is not exactly a hymn, but I have an album by a group called The Ambassadors and needed some help identifying the members on the cover. I found a couple potential people it could be. From various internet sources, I have found some potential members to help limit the search

Jim Hill, Bob Robinson, Don Butler, Bill Huey, and L.David Young

or

Jack Mainord, Howard Welborn, Roy McNeal, Earl Blackm Jeff McNeal, and Charles Cruce

Here is the picture: http://i.imgur.com/8httUjP.jpg

I think the one on the bottom right looks like Howard Welborn, but other than that I haven't been able to find much.

Thanks for any help
