Mac and 10 of the DJs on the station including Norman Jay, Jonathan More, Colin Faver, and Trevor Nelson would become 'shareholders' in a company called Goodfoot Promotions, with Mac heading up the station as its majority holder. By 1988, Kiss was at its strongest with a DJ line-up which had become the cream of London's clubland, and in that December, Mac and the other shareholders would announce that they would decide to close down in order to apply for a legal licence. This was in response to the UK Government and Independent Broadcasting Authority (IBA) announcement that 20 new "incremental radio" licences would be advertised including one for London. Stations were told that they would have to voluntarily closedown when applying, and so on New Year's Eve 1988, the final broadcast went out with an outside broadcast at Dingwalls.
