When I was a missionary, Elder Hugh B Brown of the 12 Apostles came to visit us in Raleigh and during his talk indicated that when we got home and found our eternal companion he would perform the sealing in the Temple if we were to ask him.
I called him and arranged for him to perform the sealing. Two weeks before our sealing his secretary called and said that he had accepted another assignment and could not perform the sealing for us. Then she said that some other General Authority would be happy to perform that for you. She told us that LaGrand Richards was available and would be happy to perform our sealing for us.
