I thought that was standard distribution to aspiring pipers. If it isn't, it should be.I've never heard of the Peter O'Loughlin tape.
Peter O'Loughlin recorded Tommy Reck at home during the early-ish sixties. It's a piping classic. I believe JOBM cited it on one of his recordings as Seán Reid distributing copies (the recording was sometimes associated with Reid for that reason). There are often a few tracks recorded from Reck's radio appearances at the time included with copies of it.
