I have probably missed out a few, but I can only include performers I've seen.
I saw Mathew in the fabulous Urinetown as Bobby Strong. His cute and charming characterisations of Bobby were so endearing that I was sad when he met his untimely and very gory death.
The first entry on my list from this multi award winning revival. I really like Brammer's strong and manly performance and absolutely loved his interaction with the legend Lea Salonga at the 25th Anniversary Gala.
What's on Stage award winner Kwang Ho Hong is a mega star in his homeland of South Korea. His portrayal of the Commissar Thuy in Miss Saigon has the perfect balance of being menacing but still making you feel sympathy for the character. I also loved his rendition of the Les Miserables classic, 'Bring him home' at Hugh Maynard's recent Album launch.
Hugh's smooth and rich voice make his John a real treat. With a newly released solo album, Hugh is showing his depth and creativity as a performer.
Sear's Cunningham is sweet, and just so lovable. He's like your favourite Teddy bear, with the added bonus of making you laugh.
Although a relatively small role Olivier nominated Pennycooke really stood out for me in Memphis with his charming and cheeky portrayal of the cleaner come DJ, Bobby.
Donnely has all the of the elements of a real star. Great voice, great timing and in Memphis, a wonderfully sensitive connection with the audience.
Argentine superstar, Raunch was a revelation for me when I watched the show for the third time last year. Beautifully smooth and melodic, Raunch's 'Music of the night' is wonderful.
They say your eyes are a window to your soul and Lockyer is able to portray pain and loss with one look. Fabulous depiction of this classic role.
Olivier nominated Briones has transformed this otherwise 'all so ran' character into the Peter Pan of Saigon. Not too sleazy but instead funny with just enough sentiment, Briones has my vote for the best actor in a musical gong.
These are my top ten but who are yours? If I've missed some of your favourites, would love to hear from you on Twitter.
