No signs of sickness from Adam. Here's my video selection:
Whole Lotta Love - 'Woman', 'backdoor man', lots of improvised riffing.
Mad World - Started with one foot on higher stool rung.
Slow Ride - More singing with arms round each other.
Fame & Let's Dance - Huge riff at end of Fame, sings 'happy birthday to you' to the backing singer, fitting it into the melody.
