The singer/guitarist and his bandmates were signed to the same record company as the Wonderwall hitmakers, and their labelmates' commercial success produced huge profits for the firm.
Super Furry Animals became known for their eye-catching stunts including adorning their stage with huge inflatable creatures and arriving at U.K. festivals in their own military tank.
Now Rhys reveals the band funded their lavish spending with the cash pouring into Creation Records' coffers from Oasis' huge album sales.
He tells Uncut magazine, "We were very ambitious... We were quite demanding and on some weird swindle trip. We had no respect for the industry. We could ask Creation for a tank and they'd say: 'Yeah, no problem.' Ah, and we really need two inflatable 40-foot bears. 'Yeah, we can really see that.' They gave 100 per cent of their passion."
