Time is a fantastic cover! But gotta go for OOTB because to me it's THE classic ELO cover.
It probably is the most iconic cover, but it started a never ending trend that continues to this day. What makes it worse is virtually next to no one knows or remembers who the personnel of ELO were or what they looked like... but they sure know about the saucer.
