Jethro Tull on the road playing Zappa and Gentle Giant?

Is this a joke? In a YouTube video Jethro Tull leader Ian Anderson announces a surprising setlist for the UK shows of the Prog Years tour in September.

How about Ian Anderson and Jethro Tull performing Bruce Springsteen's Born in the USA, The Advent of Panurge by Gentle Giant and (as an encore) Frank Zappa's Dinah-Moe Humm?
Not many Tull songs on the setlist, Ian. 
But the Radio Dupree staff is excited! And since we have tickets for one of the shows in northern Europe early 2022, we will find out if Ian and the lads really can bring out the Stairway to Heaven.
