Also, think about the musical elements: tempo, key, instrumentation. How the sheet music reflects a rock sound versus a hymn. Maybe talk about the arrangement, chords, rhythm, vocals. How the sheet music would guide a player to perform it in Ruth's style.

Wait, I should make sure the facts are correct. Ruth Buchanan's version was released in 1962, right? It was a top 10 hit in the UK. The song was originally a gospel hymn, written by Augustus Toplady in 1776 and set to music by John B. Dykes in 1866. Ruth's version was a rockabilly or rock and roll take, which would have been quite different from the hymn version. That's a key contrast. The sheet music for her version would reflect that arrangement, which is what's exclusive here.

Alright, "Rock of Ages" is a traditional hymn, but Ruth Buchanan did a rock and roll version in the 1960s, which was a hit in the UK. It's different from the traditional hymn version. The user wants a feature on sheet music, specifically exclusive to Ruth Buchanan's version.

Need to avoid any confusion with the 2009 musical "Rock of Ages," which is a different thing. Make sure to clarify that this feature is about Ruth Buchanan's 1960s song.
