This was the biggest hit for Saga, a Canadian band that incorporated elements of progressive rock into their pop sound. Lead singer Michael Sadler
wrote the song with his bandmates Ian Crichton (guitar), Jim Crichton (bass), Jim Gilmour (keyboards) and Steve Negus (drums).
Sadler told us: "'On the Loose' is blowing off steam. Everybody's got to just let it out every once in a while, you can't keep things inside. You know: tonight I'm on the loose, we're on the loose, you're on the loose. It's as simple as that.
At the time, and it's just gotten more so, stress, stress, stress for everybody, every single human on this planet. Every once in a while we've got to let go and just blow it out and deal with the consequences later. You've got to open that valve every once in a while."
