This is The Type Five, the band I play guitar with, filmed at a practice session shortly before The Lock Down.
The tune (what I wrote) is 'Tube Alloys', and aural trip through the sorry tale of the British atom bomb programme.
Points of interest: i) I'm using my early 90's Epiphone Les Paul Special DC and ii) I', wearing a hat indoors due to the arctic qualities of the practice space!
