Arrangement, Lead and Backup Vocals, Lead and Rhythm Acoustic Guitars, Bass Guitar, by Avigdor Zeitlin.
The melody of this song is that of “Rocky Top”, an American country and bluegrass song written by Felice and Boudleaux Bryant in 1967 and first recorded by the Osborne Brothers later that same year.
The lyrics are from the Sheva Brachot, the seven blessings recited during the Chuppah wedding ceremony and again during the week after the wedding.
Translation of the blessing is as follows:
(Blessed are You, L-rd our G‑d, King of the universe,) who created joy and happiness, groom and bride, gladness, jubilation, cheer and delight, love, friendship, harmony and fellowship.
