By Kind Permission Of lyrics

[Introduction:]
Please, let's have a big welcome for Jethro Tull.
Whoop!
Hello. Hang on, press on. Be back with you in a minute.
I'd better not open this now because it might contain contraband.
We'll give it to John to supplement his camels. He dropped on his
head when he was very small. We occasionally cut his fingernails off
and smoke them. This is a... a song about... about everything.
