It's all in the key change, folks.

If you'd wondered just how big Adele has become over the last year or so, here's your answer - although we're not sure that she'd take the phrase 'They'll be singing your songs in courtrooms around the world' as a compliment.

A criminal up on charges in a court in Ann Arbor, Michigan offered a musical apology to the judge, singing a song that sounded suspiciously like it was inspired by Adele's global smash 'Hello'.

According to the Ann Arbor News, 21-year-old Brian Earl Taylor - who was being charged with unlawful imprisonment and carrying a concealed weapon - sang the song to Judge Darlene O'Brien, and the video was recorded on courtroom video, as his lawyers and the people gathered in the court shifted uncomfortably.

His own lyrics went:

"Hello there, your honor
I want to say I'm sorry for the things I've done and I'll try and be stronger in this life I chose
But I want you to know -- that door, I closed
And your honor I'm sorry, sorry, sorry, sorry
To my mother I'm sorry, sorry, sorry, sorry
To the victim I'm sorry, sorry, sorry, sorry"

Unfortunately it didn't quite work out for him, as Taylor was sentenced to 17 years - although Judge O'Brien did say he was 'obviously a talented young man'.
