Chris is correct. In fact two new companies were formed with the Gunnels, Ronan and his PA (Oonagh) as directors and they understood promo work for several artistes. R O A R undertook promotion and publishing for a number of releases.

The statement about "plays on Luxy anyway, as it was released on EMI / Decca who block booked programming", is not necessarily so. Releases on all EMI and Decca labels were often (75% or so) released under licence, and it was down to the licensor (such as Joe Meek, etc) to arrange their own promotion. Sometimes the big boys might handle it with their own 'wholly-owned' releases, but they were expensive and you might find that promotion work was done by a number of interested parties - the artiste management, the publisher of the A side, the publisher of the B side, etc.

Dave Clark never made a record for EMI, or its Columbia label. He paid for his own studio time and owned the tapes, which he LICENSED to EMI, who released them on their Columbia label.

The Moody Blues are a prime example too; all the work on their singles, from Go Now onwards, was done from a small office in Caroline House.

Many of the big labels sub-contracted out their promotional activities to independent "pluggers", especially to get radio and TV exposure, a bit of an "old boys network". CBS did a lot of that; hiring several ex-offshore DJS. A good example is Ross Brown and Guy Blackmore from Caroline, who set up a Plugging Company called Kandoo. They steered.
