There still is considerable bad blood between Patti and ALW. However, "Don't Cry For Me Argentina" is her signature tune and she still sings it in her concerts. Rarely, if EVER, will you hear her sing anything from SUNSET BOULEVARD.
Incidentally, the swimming pool in LuPone's Connecticut home is named the "Andrew Lloyd Webber Memorial Swimming Pool". She had it installed with the settlement money she got when Webber dumped her from the Broadway show.
