New technology is now in play here at RockHistory.co.uk and just a couple more interviews have been managed over the last week – two more for the Harvest Records canon and more with other subjects including Queen, Bat Out Of Hell and Britney Spears. Plus and EMI Records reunion of staff from the middle period of the Seventies. Oh what fun. This photo is from 1973 and the equipment on that Lord Mayors float went on to provide playbacks of the Dark Side Of The Moon album to student gigs around the country as the Floyd were not touring to promote it.
