My Lost Treasure: CSN, and I’m Pretty Sure Y

Since we're working on a theme of boats and ships (all part of our transportation theme), and it's the anniversary of Woodstock, I have a perfect song for My Lost Treasure.  It's Wooden Ships performed by CSN, and I think Y at Woodstock.

I know that Neil joined CSN on stage at Woodstock during the acoustic set, and stayed for the electric.  I'm having a hard time figuring out if he was actually on this song, but I think he was.  The song was written by David Crosby, Stephen Stills, and Paul Kantner from Jefferson Airplane.  The Airplane was also at Woodstock.also at Woodstock.

Tomorrow, we'll feature another ship/boat song from a band that was at Woodstock.  They performed it there, too.  Happy Woodstock Anniversary!  Peace and love!
