Luckily, the album's engineer Alan Parsons (of The Alan Parsons Project fame) happened to know a female singer who could do what the band wanted — Clare Torry who, at the time, was a session vocalist with few credits to her name. As per Far Out Magazine, Torry was brought in to record the track and was instructed by the band members to think about dark subjects like death while she improvised her vocals. In just two-and-a-half takes (Torry stopped midway through her third take as she felt she'd already given everything she had), she produced the powerful vocals that would become defining to the song. Torry was so kept in the dark about the project that she didn't even know that her voice had ended up on the album until she bought the record at the store and noticed her name in the credits. Far Out Magazine features Torry's fascinating account of recording the song in the studio with the band: Apparently, Torry's first attempt at singing over the track was shot down because she was articulating actual words, and was directed to sing longer notes. She stated, "that was when I thought, 'Maybe I should just pretend I'm an instrument ... Alan Parsons got a lovely sound on my voice: echoey, but not too echoey. When I closed my eyes –- which I always did -– it was just all-enveloping; a lovely vocal sound, which for a singer, is always inspirational."
