The choir became a commercial and critical success when, in 1959, its rendition of the “Battle Hymn of the Republic” reached No. 13 on the Billboard Top 40 and won a Grammy the next year. However, in 1964, then-church president David O. McKay described the invitation to sing at Lyndon Johnson's inauguration as the “greatest single honor that has come to the Tabernacle Choir.” Since then, the choir has become the de facto house band for presidential inaugurations. (Well, for Republican ones, at least. Since 1964, it has performed at the first inaugurations of every Republican president, but no Democrats.) It's a role that the choir and its church have relished.
