She spent 11 happy years with Brian Rix’s company in the Whitehall farces, joining in 1954 for John Chapman’s Dry Rot, which ran for more than 1,400 performances. These comedies were also televised, and she appeared in episodes of the one-off comedies in the series Dial RIX (1962-63), with Rix and his wife Elspet Gray. Rix used to say that Hazel had the best double-take in the business.
