Toyah willcox and robert fripp have added a new twist to their sunday lunch series

I'm not aware of any information about Toyah Willcox and Robert Fripp having a "Sunday Lunch" series. Toyah Willcox is a British singer-songwriter and actress, and Robert Fripp is a British musician and guitarist, best known for his work with King Crimson. While they may have collaborated on music projects or performed together in the past, I'm not aware of any specific series or project they have worked on together called "Sunday Lunch".

If you could provide more context or information about what you're referring to, I'd be happy to try and help you further!
