Someone needs to make a translation of the entire article. Not sure exactly what he is apologizing for or if he is actually apologizing?
Not worth the effort. I'll make a summary. After the Billy Joe line, each line is about a paragraph:
"We'll come back soon"
"How was he dressed, sung some songs"
"Fans were looking, waiting for the top hits, yadda yadda"
"Pretty song, people cheers"
"Thank you, buy our new record"
"Strange looking person with a blue stripe on the face"
"More pretty songs"
"Popular song. Applause"
"Two songs more"
"Singer explains what the last songs mean"
At this point the article talks about "Kenneth". I somehow assume Stipe didn't describe it as "A song about a silly anchorman who talks about fake memos and attempts to influence elections".
"Another pretty song"
And that's it. No further explanation about the apologies.
The article doesn't say what he's apologizing for --- the rest is just about his career and songs.
