Dear brothers and sisters,
I found the answer to my own question years later. Orr's testimony of having an experience of the Holy Ghost is here:

Reading my old post, I should have explained, in humility, what is meant by a testimony of being baptized by the Holy Ghost. Orr explained it very well in the above testimony. Though he was saved, he felt a great need in his life, and felt that there was a cloud between him and God. After searching his heart, he talks of an experience that he rarely mentioned. He believes he was then given the gift of faith.
R A Torrey discussed in "Why God Used D. L. Moody" that Moody said the following to him: "Torrey, I want you to preach on the baptism with the Holy Ghost." There is much material on Torrey and Moody and being baptized by the Holy Spirit, including the fact that Moody did not understand what that meant when he was told about it.
According to Torrey: "(Mr. Moody very seldom told this and I almost hesitate to tell it) and in the midst of the bustle and hurry of that city his prayer was answered; the power of God fell upon him as he walked up the street and he had to hurry off to the house of a friend and ask that he might have a room by himself, and in that room he stayed alone for hours; and the Holy Ghost came upon him filling his soul with such joy that at last he had to ask God to withhold His hand, lest he die on the spot from very joy."
I think Paul Washer has a similar testimony. If I find it I will post the link.
God bless,
Hal
