Tunes from the Past- "Sugar Mountain"

Is it just me or is Neil Young's "Sugar Mountain" one of the saddest songs ever? I grew up with a lot of Neil Young because my dad loves him. I've always really liked this song...probably because its about growing older. I read something where Young said the song was inspired by a club that was for underage kids that he was no longer allowed to attend after he turned a certain age. I thought that was interesting because I've always wanted to be older than I am. (UNTIL NOW..all of the sudden I feel old as f*ck!-- I feel like none of my birthdays matter until 30..WHATS UP WITH THAT)
anyway: TAKE IT AWAY NEIL...
