1. Genius eclectic score by the young Leonard Bernstein.
Everything from Jazz through Conga to Lyrical Irish via Ballads and comedy numbers. All this interpreted by the Halle and their extraordinary Maestro Sir Mark Elder.
2. The book and lyrics.
These two are in the same class as Guys and Dolls - in that the songs are as memorable and the book is vibrant and keeps going at a frantic pace.
3. It is a dancefest.
And all of this is superbly delivered by brilliant choreographer Andrew Wright fresh from his current West End smash Singin' In The Rain.
4. A superb cast.
Not only do we have the charismatic Connie Fisher who delivered as Maria in The Sound of Music but also Michael Xavier who broke many a hit in the underrated Love Story in London.
5. New York, New York!
It spectacularly recreates that Wonderful Town - New York in Simon Higlett's set and costumes and binds the parts into a whole which shouts Life Force.
Wonderful Town is at the Lowry from 31 March - 21 April.
