The lyrics "When I was a child I had a fever/My hands felt just like two balloons" are autobiographical. "I remember having the flu or something, an infection with a temperature of 105 and being delirious. It wasn't like the hands looked like balloons, but they looked way too big, frightening. A lot of people think those lines are about masturbation. God knows why." - Roger Waters
"That'll keep you going through the show," that comes from a specific show at the Spectrum in Philadelphia (June 29, 1977). I had stomach cramps so bad that I thought I wasn't able to go on. A doctor backstage gave me a shot of something that I swear to God would have killed a f---ing elephant. It rendered me almost insensible.'' - Roger Waters
''This song can be divided into two sections: dark and light. The light are the parts that begin “When I was a child…,”; the dark are the “Hello, is there anybody in there” parts.'' - David Gilmour
