If you are not interested in producing a full length musical but may be looking for solo performance concert material, I've prepared these 12 music albums containing selections of some of the show songs. 
They cover a wide range of moods from pop style ballads to light classical, also songs for choirs and could be additional source to add to your repetoire. 
​
They are all 'for sale' and available for downloading as PDF files in A4 size from:- https://www.sheetmusicplus.com/publishers/tyne-music/17111
