The H&M global christmas advertising campaign 2015 is built around the brand new Katy Perry song “Every Day is a Holiday”, written by Hal Ritson together with Duke Dumont, Katy Perry and Sarah Hudson and produced by Duke Dumont and Hal Ritson.

The 4 writers holed up in the legendary Conway Recording Studios in Los Angeles for a week in the flaming heat of the California summer to develop and record the song, with Perry’s team decorating the studio in genuine vintage christmas decorations, and video footage of snow and log fires running on the studio monitors to get the right vibe going!


When your derp squad writes a Christmas song in August ???
