What if..

Was at a Jethro Tull concert last night, and I must admit they rock even after being 35 years in the industry. They ofcourse sang most of their hits like Aqualung, Locomotive breath, Budapest etc.

After 2 hours they closed the concert, bid the audience a good night and "walked" off stage. For those who have attended concerts before would realize that most of the time there is demand by the audience for an encore and the artists then happily walk back onto stage. Of course the artist expects the audience to call them back on stage, it of course confirms their star status and gives a signature of approval to their performance.

But what if they expected an encore and the request didn't come...

Why this question? Simply because expecting that the audience will call them back, the artists keep their best song at the end for the encore perfomance so that they can sign off on a high note.
