With its countrified main hook, timeless lyrics and catchy chorus, Glasgow band the Bluebells must've known they were on to a winner with Young at Heart.
And so it proved upon the now iconic song's original release when it saw the group claim their first top ten hit, peaking at No.8 in July 1984 - but there was even better to come.
Good things come to those who wait, or so the old Guinness telly adverts taught us, and, speaking of which, it was a TV commercial that would propel a reissued version of the tune to the toppermost of the poppermost of the UK charts on April 3, 1993. It would stay at No.1 for an incredible four weeks, thereby earning Young at Heart earworm status for eternity.
