Which classic rock song opens with the words: "There's a lady who's sure, all that glitters is gold"?

"There's a lady who's sure all that glitters is gold" are the opening words to Led Zeppelin's 'Stairway to Heaven'.

"Stairway to Heaven" is a song by the English rock band Led Zeppelin, released in late 1971. It was composed by guitarist Jimmy Page and vocalist Robert Plant for the band's untitled fourth studio album (often called Led Zeppelin IV). It is often referred to as one of the greatest rock songs of all time.

The song has three sections, each one progressively increasing in tempo and volume. The song begins in a slow tempo with acoustic instruments (guitar and recorders) before introducing electric instruments. The final section is an uptempo hard rock arrangement highlighted by Page's intricate guitar solo accompanying Plant's vocals that end with the plaintive a cappella line: "And she's buying a stairway to heaven."

"Stairway to Heaven" was voted number three in 2000 by VH1 on its list of the 100 Greatest Rock Songs, and was placed at number 31 on "Rolling Stone's 500 Greatest Songs of All Time". It was the most requested song on FM radio stations in the United States in the 1970s, despite never having been commercially released as a single there. In November 2007, through download sales promoting Led Zeppelin's Mothership release, "Stairway to Heaven" hit number 37 on the UK Singles Chart.
