That brings back so many memories. My first job - discounting a short-lived and deeply undistinguished spell in the old RCA press office - was at Tower.
I worked at their store in Piccadilly Circus, London. In some ways those were the best days. We were paid rubbish money, worked 80 hour weeks, and did lots and lots of very naughty things. But it was great. I was in heaven.
I started work there about six weeks before the store opened, so we were basically filling the place up with stock - mostly vinyl (it was 1986) but also a lot of tapes and CDs. We used to get a 28% discount on all purchases so there was ample opportunity to build up a good collection. In my two and a half years there, I rose to the position of night manager/assistant manager, lead buyer and head of the Tape department.They were often crazy times - there was an armed robbery, I threw Axl Rose out of the store, my then-girlfriend and I got arrested for smoking dope in our lunch hour, I got severely done over by a bunch of Newcastle fans one afternoon, I met David Bowie, took Prince and Michael Jackson after-hours shopping... so many memories.
I also got a foothold in the music press while there, and made some great friends, a frighteningly large number of whom are now dead - from AIDS, drug abuse, etc. But hell, we had some laughs.
The main qualifications one needed to work there were flexibility and a love and knowledge of music, be it rock, jazz, world, classical or shows.
If you can think about working in the centre of London, being surrounded by (mostly but not exclusively) young music-mad people... it was heaven.
That video bought back so many mermories - on a Monday, when the new releases came out, we'd all be wheeling trollies of vinyl and CDs about, stuffing the racks before the shop opened. Great, great days.
Thanks for posting the vid, which put a big warm nostalgic smile on my face.
Oh how I wish we could turn back time.
