What songs on Pink Floyd's The Wall did Toni Tennille sing back-up on?

Answer 1

Toni Tennille (of 70's group the Captain and Tennille) is credited for vocals in the liner notes.

According to Bret Urick's website, Session singer Jimmy Haas, who is credited with backup vocals on the Wall, says that while Toni Tennille, The Beach Boys and others originally provided backup vocals on the Wall, their parts were ultimately scrapped and re-recorded using Haas and three other backup vocalists. Haas asserts that "We [the four session singers] re-did everything that was on tape up to that point. Some of it was just bare ideas that Roger had, but the intonation and flow just wasn't there, at least on the Beach Boy parts. The only thing I recall Toni on was a bit of 'Goodbye Blue Sky.' She may well have done more, but once Roger and David got our first tune in the can after about an hour's work, they erased everything [the previously recorded Beach Boys and Tennille vocals] and started over."
