Sometimes credited as Groove Groove Melody, the group also produced the 1989 single "Vocalizado" for the Italian vocalist Robby Magno. They also released a maxi single "Airport '89" using the name Wood Allen, which reached No.99 in the UK singles chart.
On listening to the track again for the first time in many years, it has made me realise just how much energy the dance music scene had back in the late 80s. The house sound was very fresh sounding back then, and I'm so grateful to have been their at the start of it all.
