In August 1968 at the same time as the break-up of Mythology, another Birmingham band called Rare Breed also broke up. Vocalist Ozzy Osbourne joined with Iommi and Ward after the duo responded to an advert in a local music shop proclaiming "Ozzy Zig Requires Gig – has own PA".[26] Requiring a bassist, Osbourne mentioned his former Rare Breed bandmate Geezer Butler, who was subsequently hired along with slide guitarist Jimmy Phillips and saxophonist Alan "Aker" Clarke.[27] The six-piece band were named the Polka Tulk Blues Band.[27] After just two gigs (the last of which was at the Banklands Youth Club in Workington), Phillips and Clarke were dismissed from the band, which soon after shortened its name to Polka Tulk.[28]
