Songfacts®:

• This was the A-side of an EP, Quo Live, that was released to celebrate Status Quo's 13th anniversary. All of the tracks were recorded live and were taken from concerts at The Kursaal, Southend on March 1, 1975 and Trentham Gardens in Stoke On Trent the following night. Many predicted such a release would be a failure, but it became the first EP to reach the UK Top Ten for several years.
• The song is a Quo rarity in that it is jointly credited to Rossi, Young, Lancaster, Parfitt and Coghlan. "Everyone thought they'd written it," Francis Rossi laughed years later by way of explanation.
• Rossi did write the lyrics, which despite the seemingly bawdy song title was actually pretty innocent: "I can't overtly write a sexy lyric. My wife at the time used to sleep on my side of the bed," he told Classic Rock magazine. "The 'drink cool from the fridge' was a f---ing bottle of milk she'd left on the table that had gone warm – it was all true!"
