I was sent these files as performed by "Ludwig Van Beethoven". For quite obvious reasons, Discogs only lists one and only Ludwig Van Beethoven. Further researh resulted in the correct name and link -
https://www.discogs.com/artist/591221-Beethoven-2
- with a quite sad resume:
British guitarist. Auditioned unsuccessfully as a second guitarist for the Sex Pistols in reply to their advert in "Melody Maker" (27 September 1975, page 56). Played with Gloria Mundi but was asked to leave the group before the release of their "Glory Of The World" single (October 1978).
Just to pay tribute to a (probably) lost music genius of 80ies, here are all his 4 tunes listed in Discogs:

If you know of his further music career, please share with us.
