ok, nothing came up for the first one (the nearest I could find is Dyna JG 539-1 which is Ken Parker - It's Alright)
WR 2 is Ansell Collins - Point Blank on Wind pre (prod W. Riley)
TMcD 4575-A is Tesfa McDonald - On To The North on Tesfa (prod. TMcDonald) so 4576-B will be the version of this
Glad to be of help!
