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
