Marks & Spencer 'eggs' by RKCR/Y&R

M&S is launching two food ads as part of its commitment to selling and using only free-range eggs and no artificial colours or flavours throughout its product range.

In "eggs", set to 'Mellow Yellow' by Donovan, the familiar Dervla Kirwan voiceover informs viewers that M&S believes there's only one way to do an egg, and that's free range.

A separate ad, called "colours" and accompanied by Cyndi Lauper's 'True Colours', informs viewers that M&S Food is free from artificial flavours and colours.

It is accompanied by a series of evocative shots showing carrots, raspberries, asparagus, ice-cream, sweet-and-sour sauce and cakes.
