I was inspired recently to dig out my old Soul 45's that I had collected avidly over a number of years and then subsequently haven't touched since I moved house about 4 years ago. The fickle nature of a music collector.
Most of the mix is played off of original 7" records with a couple of LP tracks and a cheeky MP3 thrown in towards the end. Mostly this is where I don't have doubles of the 45 two parters.
You'll have to excuse the quality on a couple of the tunes but the vinyl is the best part of 50 years old! I think the integrity of the music allows for it anyway.
