MSR Records was a DIY Reggae label. All of the MSR singles had a large spindle-hole, presumably to give them a Jamaican appearance, 'Do Good' by Tyrone & The Mighty Soul Rebels, was a singles with small spindle holes so sum do exist.  There were at least seven releases on MSR, one of which was only available as a 12" single.  Five of them of  featured the Mighty Soul Rebels or the Soul Rebels (reportedly a precursor of that band); presumably the label belonged to one or more of the band members.  Numbering is confused: two of the singles were numbered in the MSR-000s, another was numbered MSR MA-1, and two others had no numbers at all.  The latter two did however have Lyntone matrix numbers, as indicated in the discography below.  Similarly, dating is generally absent, but MSR-001 had a year on the label, 1976, and the Lyntone numbers enable us to date two of the others to 1977, which gives us a reasonable idea of the span of the label's operations.  The Rebels were from London; founder member Leon Leiffer went on to be one of the Blackstones. Distributed By MSR Records.
