Beat Rhythm Fashion release, and Barry Plankton puzzle

Yayy this week arrived my copy of Failsafe Records' new CD collecting the lost singles of early 80s Wellington band Beat Rhythm Fashion with their vast echoey chilling postpunk sound. The iconic, bewildering, gloriously dark song 'Turn of the Century' from 1981 is more distant from the insistent early 'Seventeen Seconds' Cure model of some other tracks. Great work by Failsafe.

But here's a puzzle that some Melbourne and Kiwi postpunkheads must be able to settle. Peter at dub dot dash passed on here the second-hand news that the brothers in Beat Rhythm Fashion, Nino Birch and Dan Birch, 'ended up in Melbourne, playing in a band called Barry Plankton'. Is this true? This link was how I found BRF in the first place, searching for Plankton time and their (equally lost, or more so now) 1991 record Sea Brains, which is sunny and magical and utterly diverse, 17 swirling pop songs just janglysmart enough, with three or four transporting tracks at the heart of the album - 'Walking Alone', 'Everyday', 'Dreaming is Easy', 'Major Drug' - which outdo There She Goes or any of the other perfect pop of the era. I saw Barry Plankton with their five singers in 1992 playing their guts out for maybe 20 people in Adelaide at the fringe club but I didn't say 'thanks!'. Anyway my Sea Brains album doesn't give the names of the band members, and the problem with the Birch bros story is that insistent googling comes up with four other guys who were in Barry Plankton: Bryan Colechin (Hugo Race), Des Hefner (Birthday Party), Wayne Drury, plus a Marty P. So unless two of those are the same person, then the two Birch bros couldn't have been in the 5-piece too. What's the truth?
