Regardless of how thoroughly you've rehearsed, there's always the possibility of a wild card, and it came in the form of a possibly indigenous female interjector. Leonard was doing his eighties basic synthesizer shtick on Tower of Song, and making wry remarks that fitted immaculately alongside the line about having no choice and being born with the gift of a golden voice when the interjections came.
The keyboard doodling and noodling continued, but Leonard was late back into the next verse. He seemed to be giggling.
It didn't, however, seem to throw the Webb sisters, who were on stage in the trimmed down Tower of Song ensemble straight after the resumption. They were magnificent throughout, and shone on If It Be Your Will.
