Re.Rolf Harris and Stairway To Heaven - leaving aside the difficulty in seeing him knowing what we know now -
this song does not exist in isolation.
It is one track on a 22-track album called The Money Or The Gun - derived from an Australian TV game show of the same name.
The producers hit on the novel idea of having a musical guest each week who would perform Stairway in their own individual style.
So - Rolf Harris performed in his own style, and Elvis clone did it in the timing of Viva Lass Vegas, The Beatnix, a Beatles cover band did it like it was I Wanna Hold Your Hand, the Australian Doors did it like Light My Fire, the list goes on, and the song works in every single style.
Prince recorded a version, but his was never broadcast - it was so amazing it was believed it would put anyone else off from ever trying the song again!
For the record, I absolutely adore Rolf's version, I saw him do it live at Glastonbury - and I am able to separate the art from the artist - whatever we know about Harris as an individual, does not detract from the cleverness employed to make this song.
