The missing verse (available in the bootleg) is two after the one you cite ("The backstage manager" verse comes first):

Lily's arms were locked around the man that she dearly loved to touch,
She forgot all about the man she couldn't stand
who hounded her so much.
"I've missed you so," she said to him,
and he felt she was sincere,
But just beyond the door he felt jealousy and fear.
Just another night in the life of the Jack of Hearts..
,br>yours, Peter T. P.S. If that fills in your logical gap.
