Listening to the album 'Comedy' by Paul Kelly & the Messengers, I'd completely forgotten there was a hidden track at the end.
After the end of the last listed song, there's a longish gap, then the band kicks off a (possibly beer-fuelled) singalong of "One David Gower, there's only one David Gower", which starts off to the tune of 'Guantanamera' before sliding into 'I'll find my Way Home' by Jon & Vangelis.
I'm assuming, as Paul Kelly is Australian, this is a tribute to the Tiger Moth incident, rather than Gower's batting skills.
