Yep it's still going I had a look at it on Google Street View
On the subject of the Rainbow Casino, I used to live in Portland Road remember going there a few times.
This thread is really bring back memories.
Bit off topic but this came to mind.
I used to sell Hot Dogs from a barrow on pitches all over the town centre and on my nights off I went clubbing.
I always remember a bloke who also lived in Portland Road coming up to me on evening and moaning he had missed his Night Service Bus. So being the thoughtful person I was I said I'd give him a lift home. As I push my barrow down Albert Street he passed comment, I could buy and sell people like you! I thought you're drunk sunshine and carried on pushing. I arrived at the yard cashed up and went out to meet the guy who was waiting outside. He said "OK where's the wreck you're giving me a lift in ? I walked over to my nearly new Rover 2000 and said "Do you want a lift or not?" He didn't say a word save for thank you when I dropped him off.
I also knew Pat Roach and met Larry Adler, he had lost his harmonica and wanted to buy a new one urgently, so who does he ask the Hot Dog man. I told him where he could get one, a shop in Needless Alley.
I sold a hot dog to Richard Chamberlin outside the Rep in Station Street late one night.
I went to Mothers, The West End, Castaways, Snobs, Night & Day, Rebeccas, Samanthas, The Tower Ballroom I could go on but many of the clubs have already been covered.
Just a thought does anyone remember one Barry Parker?
