I love this guest appearance by Linda Lewis during Terry Reid's performance at the second Glastonbury festival in 1971.
Terry Reid was the original choice as vocalist for a band being formed by Jimmy Page called The New Yardbirds (eventually known as Led Zeppelin). Due to other commitments Reid turned down the job and suggested a young vocalist called Robert Plant.
Anyway back to Linda Lewis. She was/is a recording artist in her own right, her most famous hits being Rockadoodledoo and Its in His Kiss.
She ambles onto the stage here at 6.29. Great afro too.
