In one incident during the last few days of mixing, Anderson left the studio one morning with Offord carrying the tapes. Offord placed them on-top of his car in order to find his car keys, and proceeded to drive away, forgetting about the tapes. They stopped the car to find the tapes had slid off and fallen on the road, causing Anderson to rush back and stop an oncoming bus to save them. Yes's studio time amounted to £90,000 in costs.
