I cheated and used AI to save typing but this is the 'real' rock top ten (in layer years the first side of 2112 became a staple):
The "Friday Rock Show" top 10s from the classic Tommy Vance era on BBC Radio 1, consistently featured epic rock anthems like Led Zeppelin's "Stairway to Heaven" (often #1), Lynyrd Skynyrd's "Free Bird," Deep Purple's "Child in Time," Rush's "Xanadu," Rainbow's "Stargazer," Pink Floyd's "Shine On You Crazy Diamond," Genesis's "Supper's Ready," Yes's "Starship Trooper," and Deep Purple's "Smoke on the Water", with slight variations depending on the specific listener poll or broadcast date in the late '70s and early '80s, highlighting progressive and heavy rock.
The year that sticks in my mind (because I listened with my first serious girlfriend) was 1982:
Led Zeppelin - "Stairway to Heaven"
Genesis - "Supper's Ready"
Lynyrd Skynyrd - "Free Bird"
Rainbow - "Stargazer"
Rush - "Xanadu"
Deep Purple - "Child in Time"
Yes - "Awaken"
Deep Purple - "Smoke on the Water"
Pink Floyd - "Shine On You Crazy Diamond"
Rush - "2112"
