Idiot Wind - bad note

Been meaning to bring this up for the last 10 or so years...

There's a spot in IW just after:

"Down the highway,
down the tracks,
down the road to ecstasy... (BAD NOTE)
I followed..."

It has always, every time, sounded like one of the instruments struck
a note slightly out of key after he says 'ecstasy'. I know it's
there. It is. Um, anyone else hear it?
