Tough one today.
10 minutes good
5 minutes excellent
Below 5 superb
Letter frequency + grammar gives word after the comma.
That gives not next-to-last word, but the word before that.
It also allows a guess by grammar at words 2 and 3.
Which then gives words 9 and 11 trivially.
From there it's mopping up.
About 3 min. Lucky guess at FEX after comma. Then came playing with most likely 2 and 3 letter words. When solution became visible, made me think of the Mighty Quinn by Manfred Mann.
