British singer Bob Allison has died at the age of 72.

The star, real name Bernard Colin Day, passed away after a long battle with ill health, reports the Bbc.

He and bandmate John Allison rose to fame in the 1960s and represented the U.K. at the Eurovision Song Contest in 1961, placing second with the track Are You Sure?

The Allisons split not long after their Eurovision success, although John Allison, born Brian Henry Alford, continued to tour under the band name with various other partners throughout the 1970s and '80s.
