It's wonderful to see Kylie Minogue back in the top ten of the UK ITunes singles charts with her new single Timebomb. Many pop blogs including Popjustice are loving the Woop! part of the song.
I'm sure other pop blogs have picked up on it too but that Woop! sample sound is very similar to part of the song Let's All Chant which was a disco hit by the Michael Zager band in 1978. In 1988 Let's All Chant was covered by Pat and Mick and their version was produced by Stock, Aitken and Waterman.
Take a listen to both versions of Let's all Chant and then to Timebomb.
Here is The Michael Zager band and Let's All Chant which got to number 36 on the Billboard Hot 100 in 1978.
and from 1988 this is Pat and Mick and their cover version which got to number 11 in the UK singles chart.
and to right now here's Kylie's Timebomb.
