I whakauruhia e ratou te kaiwaiata o Geezer Butler me te kaiwaiata o Ozzy Osbourne, i takaro tahi i roto i tetahi roopu i kiia ko Rare Breed, i tukuna e Osbourne he panui ki tetahi toa puoro a rohe: "Ko Ozzy Zig Needs Gig <unk> he PA ake". I te tuatahi ko te ingoa o te roopu hou ko te Polka Tulk Blues Band, te ingoa i tangohia mai i te waitohu o te paura talcum, i te toa kakahu Inia / Pakistani ranei; he raruraru te takenga mai. Ko te Polka Tulk Blues Band i uru atu ki te kaituhituhi kiriata Jimmy Phillips, he hoa tamariki o Osbourne, me te saxophonist Alan "Aker" Clarke. Whai muri i te whakaiti i te ingoa ki Polka Tulk, ka huri ano te roopu i to raatau ingoa ki te Ao (i kinongia e Osbourne) ka haere tonu hei roopu e wha me te kore o Phillips me Clarke. I raru a Iommi na te kore o Phillips me Clarke i te whakapau kaha me te kore e aro nui ki te roopu.

Ko te taitara demo "Song for Jim" he korero mo Jim Simpson. Ko Jim Simpson he kaiwhakahaere mo nga roopu Bakerloo Blues Line me Tea & Symphony, me te kaitakaro puoro mo te roopu Locomotive. I whakatuwherahia e Simpson he karapu hou ko Henry's Blueshouse i te Crown Hotel i Birmingham, a ka tuku i te whenua ki te purei i reira i muri i to raatau whakaae ki te whakakore i te utu roopu tautoko i nga wa katoa hei utu mo nga koti koreutu. He pai te urupare a te hunga whakarongo, a i whakaae a Simpson ki te whakahaere i te Ao. I te marama o Tihema 1968, ka wehe wawe a Iommi i te Ao ki te whakauru ki a Jethro Tull. Ahakoa he poto te wa i noho ai ia ki te roopu, i puta a Iommi me Jethro Tull i runga i te whakaaturanga pouaka whakaata a The Rolling Stones Rock and Roll Circus. Kaore i makona ki te aronga o Jethro Tull, ka hoki a Iommi ki...  Pātai: He aha te ingoa o te rōpū i pōhēhētia ki tētahi atu rōpū e kiia nei ko "Earth"?
