The original Rock of Ages hymn, penned by Augustus Toplady in 1776, became one of the most beloved Christian songs, set to music by John B. Dykes in the 1860s. Its deep spiritual resonance and memorable melody transcended denominations and eras. However, Ruth Buchanan’s version, released in 1962, marked a radical departure. By infusing the hymn with a driving rock beat, electric guitar riffs, and a youthful, rebellious energy, Buchanan transformed it into a cultural phenomenon. Her version reached No. 6 in the UK charts, introducing a new generation to the song while sparking debate about the fusion of sacred and secular music.

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.

I need to start by introducing Ruth Buchanan and her rendition of "Rock of Ages." Maybe talk about the song's origins and how she transformed it. Then focus on the sheet music, its importance, how it captures her style, and maybe its exclusivity. Also, mention the impact of the song on her career and the music industry at the time. Perhaps include some historical context of the 60s music scene where rock and roll covered traditional songs. Also, how sheet music was a big thing back then compared to today's digital distribution. Maybe touch on the current interest in vintage sheet music and its collectibility. Need to mention where to find it now, like archives, collectors, online databases. Also, any availability in print or digital forms? Maybe include a quote from experts or musicians who value her version. Also, mention if there are any notable covers or adaptations since.

Today, Buchanan’s Rock of Ages endures as a cult classic. The sheet music acts as a bridge between eras, connecting a 1776 text to 1960s musical innovation. Modern covers of the song, while fewer, occasionally nod to Buchanan’s arrangement, as seen in tribute performances by rockabilly revivalists.
