That seems less likely than the list being mis-dated! While on Broadway the tradition is to officially list holiday covers as full-time replacements in that role, in the West End they don't change the cast lists, instead there'll be a slip in the programme. In fact, my July 1999 programme has slips for Kerry Washington as Grizabella, Suzanne Heyne as Demeter, and Andrew Wright as a swing.

I saw Cats in London fairly frequently between 1999 and 2002.... if only I'd kept a decent diary! There were quite a lot of cast coming and going, but even so, I think it much more likely that that 12/1999 list is mis-dated.

In fact, I can refer to at least one of those 12/1999 names - Rachel Mooney was in Starlight Express until April 2000, and I know I saw her perfoming in that show, so she couldn't have nipped over to Cats, learned the show, covered for a month, returned to finish Starlight Express.
