Who was the original Frank N. Furter in the London production of The Rocky Horror Show?

After two previews, the show premiered – without an interval – at the Royal Court's 63-seat Theatre Upstairs on 19 June 1973 and ran until 20 July 1973. The cast included Tim Curry, Patricia Quinn, Nell Campbell (billed as Little Nell), Julie Covington, and Richard O'Brien, who made the production, which was all-out camp, a creative triumph and a critical and commercial success. Record producer Jonathan King saw it on the second night and signed the cast to make the original cast recording over a long weekend that was rushed out on his UK Records label. King was involved heavily in the initial promotion for the show as well as being the minority backer of it financially.
