Greenday - Wake Me Up When September Ends

i dont know bout u all.. but after listenin and lookin at this greenday song/vid.. i felt somethin deep inside the lyric..
actually this is an old song, published by greenday on their American Idiot Album released on September 2004.
this vid also bein nominated for "best rock video" in 2006 MTV Video Music Award.. but lost at the end..
till now, when i heard this song being played in radio, i felt some weird feelin in my heart.. its kinda sad/passionate.. but... ehm..
this is what was commented in wiki bout this song;-

"There once was much debate about what this song was about, one of the most common initial beliefs, and still a very prevalent one at that, being that it is about 9/11. However, Billie Joe has confirmed to the public that the song was written as a memorial anthem about his father, a jazz musician and minor league baseball catcher, who died of lung cancer when Billie Joe was only ten years old."

Lyric

Summer has come and passed.
The innocent can never last
Wake me up,
When September ends.

Like my father's come to pass, seven years has gone so fast.
Wake me up,
When September ends.

Here comes the rain again,
Falling from the stars;
Drenched in my pain again,
Becoming who we are.

As my memory rests,
But never forgets what I lost.
Wake me up,
When September ends.

Summer has come and passed.
The innocent can never last.
Wake me up,
When September ends.

Ring out the bells again.
Like we did when spring began.
Wake me up,
When September ends.

Here comes the rain again,
Falling from the stars;
Drenched in my pain again,
Becoming who we are.

As my memory rest,
But never forgets what I lost.
Wake me up,
When September ends.

Summer has come and passed.
The innocent can never last.
Wake me up,
When September ends.

Like my father's come to pass.
Twenty years has gone so fast.
Wake me up,
When September ends.
Wake me up,
When September ends.
Wake me up,
When September ends....
