The world is wondering how Tony Sly, the No Use For A Name singer and songwriter, died, in the wake of the tragic news that he had passed away Tuesday at the age of 41.

The sad revelation that punk rock had lost one of its great song-smiths hit the web after the band's label, Fat Wreck Chords, released a statement saying as much:

"It is with great sorrow that we must say goodbye to Tony Sly of No Use For A Name. We received a call earlier today of his passing, and are devastated. We have lost an incredible talent, friend, and father - one of the true greats. Fat Mike had this to say: 'One of my dearest friends and favorite song writers has gone way too soon. Tony, you will be greatly missed.'" 

Mike Burkett, the founder of Fat Wreck Chords and the front-man of the band NOFX, is the Fat Mike being referred to in the brief statement above.

As news spreads throughout the music industry about his untimely passing, the question of how Tony Sly died is coming up repeatedly, as fans were dismayed to learn that he had passed away at such a young age.

But unfortunately, Fat Wreck Chords did not provide details about his cause of death, and there does not appear to be any official report as to what killed Tony Sly.

No Use For A Name is a seminal punk-rock group that started out in 1987 in San Jose, California. In 1989, Tony Sly -- full name Anthony J. Sly -- became a member of the band, with which he released nine records.

Tony Sly released a number of solo albums as No Use For A Name began to lose popularity in the new millennium after a good run in the 1980s and 1990s punk scene. His most recent solo release was 2011's "Sad Bear."
