"D-Days" is a song by British singer-songwriter Hazel O'Connor, released in March 1981 as a single from her second album, Sons and Lovers.

The single was produced by Nigel Gray and remixed for single release by Tony Visconti, who had produced her previous album Breaking Glass.

The song stands for 'Decadent Days' and was inspired by a trip to a night in London where there were lots of poseurs and "people looking very bizarre".

[2] Reviewing the song for Record Mirror, Rosalind Russell wrote that "the smart marching pace suits Hazel's sense of style and drama and she hasn't deviated too far from her previous material to risk failure.

[3] David Hepworth for Smash Hits wrote "eight bars into this and I'm reaching for Red Starr's [sic] Russian fur hat and cossack dancing round the office like a good'un.
