This day in music history.

David Crosby is called upon to identify her badly damaged body. The Crosby, Stills and Nash album went to #6 on the pop charts and had several hit songs, "Marrakesh Express" and "Suite: Judy Blue Eyes".

Guinnevere by David Crosby
Guinnevere had green eyes
Like yours, mi'lady like yours
When she'd walk down
Through the garden
In the morning after it rained
Peacocks wandered aimlessly
Underneath an orange tree
Why can't she see me?
Guinnevere
Drew pentagrams
Like yours, mi'lady like yours
Late at night
When she thought
that no one was watching at all
She shall be free
As she turns her gaze
Down the slope
to the harbor where I lay
Anchored for a day
Guinnevere
Had golden hair
Like yours, mi'lady like yours
Streaming out when we'd ride
Through the warm wind down by the bay
Yesterday
Seagulls circle endlessly
I sing in silent harmony
We shall be free
