John Lloyd Young is really good as Frankie. his voice was, for the most part, very strong, but it did sound quite tired on occasions, which is probably due to the tech run in the week and then the dress rehearsal in the afternoon. His acting was on another level, there was a clear progression in his Frankie from the younger Frankie to the older Frankie, which I haven't seen as clearly in many of the Frankies. He's really good at the darker and more emotional scenes - especially Fallen Angel and also the scene round the table with the other Seasons.
The rest of the cast were very good. Matt Nalton makes a very good Nick Massi, and I was impressed for what was his West End debut. His accent slipped a couple of times, and he looked like he was about to burst into a huge grin as he said he wanted to leave the group. Other than that, I was impressed with him - Jon and Edd were great as always.
Of the others, standouts were Nicola Brazil, who got a lot of laughs as Mary Delgado, but she also nailed the more emotional scenes opposite JLY. I loved Tom Goodridge and Sean Mulligan (Tom's Love Muffin scene was very funny).
Thanks for update ... sounds like a relatively easy progression from PET to Piccadilly ... long may it continue
