The interpreters work in pairs. Nancy (L) is the actual interpreter and Peg (R) is the prompter. Peg supplies words or phrases that may be difficult to hear and also especially feeds the lines of a hymn to Nancy in advance to give her an extra second or two to determine how to sign poetic phrasing.
