The site is still there... here is the pertinent copy about the PBS rendition:

On the night of January 15th, 2000, Ralph was honored by the Grand Ole Opry by becoming its newest member. The induction was performed by Patty Loveless and Porter Wagoner. During the ceremony, Ralph said "I'll carry the name of the Grand Ole Opry out everywhere that I go. I'll always respect it, and I'll never let it down."

Porter and Patty both appeared on Stanley's award-winning album Clinch Mountain Country. Patty told Ralph that "... Ricky Skaggs wanted so much to be here tonight and I'm sure he's with us in spirit, as is your brother Carter, Mr. Keith Whitley, Curly Ray Cline (longtime fiddler for Stanley who passed away in 1997) and many of the other Clinch Mountain Boys. We're all sharing this evening with you." Patty then joined Ralph to perform a hair-raising version of "Pretty Polly," which she recorded for the Clinch Mountain Country album.
