Want to correct and add to some information on Postcard.
Alan Horne and Paul Quinn are not "together" in the sense suggested. By all accounts, Alan is Paul's full time carer as Paul has a serious illness, M.S I'm led to believe. Until recently they lived together in Glasgow but I've heard they had moved to Dundee, Paul Quinn's home town, although I don't know how true that actually is.
Postcard Records was based at 183 West Princes Street, or West Princes Street of Dreams as Horne dubbed it. The label was literally run out of his wardrobe.
Horne came from Saltcoats and was studying Botany at the University of Glasgow. Most of Orange Juice came from Bearsden, although Edwyn Collins was born in Edinburgh and had been brought up in Dundee (he was childhood friends with Paul Quinn there) and then moved to Glasgow.
Early appearances included gigs at the Glasgow School of Art and Satellite City at the Apollo. Orange Juice had close connections with the music scene in Edinburgh which at the time had a better developed punk/post-punk scene, their first recordings and some of the Postcard singles were recorded there and also with the so called Punk Rock Hotel, the Silver Thread in Paisley, where Glasgow's banished punks gathered. Josef K, an Edinburgh band were the first to sign to Postcard and afterward they were joined by Aztec Camera (from East Kilbride) and Australian band The Go-Betweens who they met in London and signed to the label. For a time afterward The Go-Betweens based themselves in Glasgow. Apparently various other bands 'signed' to Postcard but didn't get the chance to release anything before the label ceased, The Bluebells being the best known. Variously other bands were closely connected to the Postcard orbit such as The French Impressionists and Strawberry Switchblade.
The Postcard label disappeared when most of the bands signed major label deals after Horne's plans to take the pop charts by storm didn't quite materialize. Officially Aztec Camera released two singles on Postcard but rumour has it they also recorded a debut album for the label that was never released. Josef K broke up with the label and The Go-Between's also split up, although they later reformed with an expanded line up and released some classic 80's indie albums. Orange Juice recorded 'You Can't Hide Your Love Forever' for Postcard but the tapes were leased to Polydor after the band signed a deal with them, therefore it was a joint released between Postcard and Polydor and features both label logos on the LP.
Horne re-activated in the early-mid '90's to release rare and unreleased Orange Juice material on CD (and vinyl) with new material from various old friends including Paul Quinn (2 excellent albums with the Independent Band, a who's who of a certain generation of Glaswegian musicians) and Nectarine No.9 (formerly Fire Engines/Win) and an album by long time inspiration Vic Goddard.
The labels last release was by rock n' roll poet Jock Scot in 1997 after which the label disappeared once again for good since its been said Alan Horne has absolutely no interest in the modern music scene. He did however appear as the 'cover star' of the Belle & Sebastian single 'This Is Just A Modern Rock Song', as far as I know his last involvement with the Glasgow music scene.
Edwyn Collins career should be well known to most. The rest of Orange Juice are now spread far and wide. Steven Daly, the drummer, is now a New York based journalist. David McClymont had written various travel guides and lives in Australia. James Kirk still lives in Glasgow and, so it's said, works as a chiropodist. Kirk, along with Daley, left the band after the debut album and formed the group Memphis who released one single. Kirk also played on the Paul Quinn albums released on Postcard and issued a solo album about 7 or 8 years ago called 'You Can Make It If You Boogie' on the German label Marina (the Germans love Orange Juice!). The album was very good. He also occasionally collaborated with Sushil Dade (Future Pilot AKA) but as far as I know he hasn't been musically active for a while, at least in terms of releasing records.
