Kerrel Records was a DIY label. Run by Bill / Billy Matthews - he was responsible for the only two releases that I have so far been able to track down on that label.  One of them, an EP featuring 'Mona Lisa', 'Morning Has Broken', 'Heard It Through The Grapevine' and a medley 'Smile / Ipanema' was made through Deroy Records, which makes it of interest to collectors of that company's products.  Its catalogue number was DER-1411, and it came out in 1978.  The other was a single, 'Axe-I-Dent' b/w 'Engraved', which had a catalogue number of WM-38 and was undated.  Presumably the 'WM' part was Billy's initials; what the '38' indicated is anybody's guess.  The single looks early '80s to me, but it's unusual enough for me to justify slipping it in here. Distributed By Kerrel Records.
