The music and lyrics of the song were improvized on stage during a concert in Southern Ontario (the guitarist, Randy Bachman, recalled it being at a concert in Kitchener, although Burton Cummings, the lead singer, said it was at the Broom and Stone, a curling rink in Scarborough). Bachman was playing notes while tuning his guitar after replacing a broken string, and he realized he was playing a new riff that he wanted to remember. He continued playing it and the other band members returned to the stage and joined in, creating a jam session in which Cummings improvized the lyrics. They noticed a kid with a cassette recorder making a bootleg recording and asked him for the tape. They listened to the tape and noted down the words that Cummings had extemporized, and which he later revised.
