If you get the 101 Greatest Broadway Musicals book, it states it in the section on Funny Girl. Fabulous book, pretty much a must if not for some of the picks (he has Cats and Phantom of the Opera, yet no Nine or Sunday in the Park with George) than for the fantastic color photos, Broadway profiles, and some very interesting backstage facts on some of the musicals. There are also one page recurring sections that pop up such as "T&A" representing sex appeal in musicals (Gwen Verdon in Redhead and Anita Morris in Nine), "Great scores from So-So shows" (Candide, Merrily..., etc.) and such.
"Sing the words, Patti!!!!" Stephen Sondheim to Patti LuPone.
