I see that Sol has given the correct info re Isla St Clair: she has indeed come full circle, starting as a folk singer before she became a TV personality alongside Larry Grayson: we have had her as a guest at our local Folk Club on a couple of occasions in the last 10 years.

Don't think anyone has mentioned Barbara Dickson? Started as a folk singer, but then had a very successful career in acting/musical theatre, including winning two Olivier Awards, but is now back doing brilliant folk concerts. Another full circle!
