I was trying to find a shop which sold second hand squash rackets in Stoke Newington when I stumbled upon Tin-Tone Guitars.
It’s worth clicking on the above link to hear their audio advert which is a masterpiece in its own right.
If you do head down to Stoke Newington it is also worth looking up Lucky Seven Records. Loads of vinyl singles 2p each – and you can spend hours checking them all out on a record player in the back room. Seriously recommended.
