Whatever band they choose - their music isn't enough to get them over the line. It has to have an associated 'story' with it. Characters and themes Stern can exploit and work with. Maiden is in front by a mile here. Existing artwork, a broad range of adventurous stories themes, times and worlds. Led Zep, Aerosmith etc is bollocks I reckon. Won't happen. Even if you aren't t a fan of Iron Maiden, as a business person you'd go with the theme that was going to bring in $.
