1927 had a huge hit in their native Australia with their debut single, Eighties anthem That’s When I Think Of You.

I’d never heard this song or of 1927, the group who made it, until it was played in the new BBC rom-com drama Mix Tape last night.

With its slow-burning build-up it’s instantly Eighties: chugging bass, big echoing drums, big clanging guitars and big vocals singing a big antheic chorus.

You can instantly imagine a pair of mopey teens making out while it plays on the stereo system at a student party – and that’s exactly how it came to my ears. Vicariously, of course.

Mix Tape is about a teenage couple who meet and fall in love at school in Sheffield in the late Eighties and exchange lovingly crafted cassette mixtapes – like we did in those olden days.

Fast forwarding to the present day (no spoilers), we wonder whether they might reconnect a quarter of a century later, living on opposite sides of the world with families of their own: he’s a music journalist in Sheffield and she’s a hot debut author in Sydney.

So it’s not exactly a surprise to learn that 1927 are an Australian band, formed in 1987, and that this song – That’s When I Think Of You – was their biggest hit.

They were formed by guitarist and songwriter Gary Frost after he left another band called Moving Pictures, for whom he had written a 1981 chart-topping single called What About Me and spotted Erik Weideman on a TV talent show, covering the Police song Roxanne.

Driving from Sydney to find him singing in a pub in Melbourne, Frost recruited him as lead singer, guitarist and keyboard player for his new band, adding, Garry’s brother Bill Frost on bass and James Barton on drums and drawing the band name 1927 from a hat of suggestions.

This was their first single, reaching the Top Five, and their debut album, …ish, went to No.1 and stayed in the album charts for almost a year. They never broke through here, though, with the single peaking at No.48.

They’re still going today with Weideman the only original member and the only constant among the ten who have passed through.
