[2] Together with keyboard player Mark Stevens, he recruited guitarist Dave Christopher, bassist Dave Green and drummer Graham Jarvis - his usual session drummer, Graham Hollingsworth, wasn't available - and booked, in his words, "the cheapest 24-track studio I could find, above a bingo hall in Clapham, London"[1] and had the track completed in twelve hours: three hours a day, for four days.
[2] However, he eventually found a wholesaler - Ray Self of the One Stop record shop in Euston Tower - who agreed to produce the first 1,000 copies as long as they were 12-inch picture sleeves.
They were printed as "dazzling, eye-catching translucent blue" vinyls with no writing on it; talking to MigMag.co.uk, he said this was because a supermarket supplier[2] "advised me that a product label is designed to get the customer to pick it up.
[1] Eventually, distribution was delegated to Pinnacle at the suggestion of Pete Waterman,[2] then a new distributor, who produced new 7-inch pressings and multi-coloured versions of the 12-inch.
This was next to impossible; though the musicians were capable of recording the backing track in one take, Gallacher and Stevens had spent days overdubbing keyboards and synthesizers, which couldn't be redone in three hours.
Gallacher was exclusively responsible for the fourth Doctor, Tom Baker, being present at the convention, as he found out that the BBC TV technicians were going on strike that day and thus asked convention producer Lucy Chase Williams and her co-producer Amy Krell if it was worth him calling Graham Williams to see if Baker could get there.
However, the follow-up, "Chain Reaction", flopped despite thousands of pounds being spent on it and it being recorded in a 48 track studio and being backed by "Funky Revolution".
[2] An extended period of time went by before Mankind was resurrected for Ovation Records,[2] for "Dark Star Angel" and "UFO", which were released in 1980 and flopped.
