The fictional Freed is an evil version of the actual Freed, who in the story enthusiastically announces the names of deceased rock 'n' roll legends in You Know They Got a Hell of a Band as part of an upcoming concert to perform.
Susannah sees an interesting poster when she's exploring with Nigel after the birth of Mordred. Alan Freed's habit of reciting dead people is reminiscent of Susannah's uncontrollable compulsion to do the same.
Nigel turned left, into a new corridor with doors on both sides. She got him to stop long enough to try one of them, but there was nothing of particular note inside.

SAY, YOU COOL CATS AND BOPPIN’ KITTIES!
I ROCKED AT THE HOP WITH ALAN FREED!
