This photo was taken from the Rare Original Cats UK PLAYBILL (1981) which is being auctioned at Ebay.com. Judi was unable to star in the play because of a torn Achilles tendon she suffered during the rehearsals. The role of Grizabella was taken over by Elaine Paige.

Read the transcription of the biographical notes which appeared in that playbill. I included the photo which appeared in the playbill, but it was quite difficult to read -- hence the transcription.
