Musical Play CATS

I always admire the voice of Leah Salonga, though she's not a "birit queen" her quality of voice was highly acclaimed around the world making her famous in Miss Saigon. I will always remember her in the song "I Am But a Small Voice". She's a very down to earth lady but I was puzzled why she was not invited to sing our National Anthem on Pacquiao's boxing matches. I heard good reviews of her in CATS, I want to watch the play but the tickets are very expensive. I just want to wish her luck and congratulations on their successful musical play.
FYI, Cats is a musical composed by Andrew Lloyd Webber based on Old Possum's Book of Practical Cats by T. S. Eliot. It introduced the song standard "Memory".

It is currently the 2nd longest-running show in Broadway history and the 4th longest-running show in musical theatre history.

The musical first opened in the West End in 1981 and then on Broadway in 1982. Each time directed by Trevor Nunn and choreographed by Gillian Lynne, it won numerous awards, including both the Laurence Olivier Award and the Tony Award for Best Musical. The London production ran for twenty one years and the Broadway production ran for eighteen years, both setting long-run records. Actresses Elaine Paige and Betty Buckley became particularly associated with the musical. One actress, Marlene Danielle, performed in the Broadway production for its entire run (from 1982 until 2000).

Cats has been performed around the world many times and has been translated into more than 20 languages. In 1998 it was also made into a television video. source: wiki
