I have been perusing iTunes and searched "Sondheim" and there are several recordings that are listed as "partial albums." The live concert version of
Anyone Can Whistle, Bernadette Peters' version of "The Legends of Broadway," the Leicester Haymarket production of
Merrily We Roll Along, the original Broadway cast highlights release of
Sweeney Todd and the OBC recording of
Into the Woods are all available (on iTunes) only as "partial albums."
Anyone Can Whistle has tracks 1, 3, 8, 11, 13, 15, 17, 19, 20, 25, 26 and 27. And
Into the Woods only has tracks 9 and 14!!

What's that all about??
