Simply put, it was the loosest Dylan has seemed onstage in many years.

A spontaneous decision after finding a wrench on his piano?

Still in shock, they wrote on Instagram.

Today has officially become one of the most unforgettable days of our lives.

Feeling beyond grateful for this moment, this tour, and all the love and support weve been shown.

Thank you, Bob, for making this dream even more surreal.

(They shared the photo, which is a rare chance to see Dylan in his offstage duds.)

It wraps on Nov. 14 at Londons Royal Albert Hall.

Lets hope the tiny wrench makes another appearance at some point.

Theres a lot more he can do with that thing.
