I believe I attended this concert on Sept. 7th, 1973. I remember the house went dark at a certain point & thousands flicked their lighters. Some kind of pro-marijuana demonstration. I forget whether I went to see the Dead at RFK Stadium in DC before or after this concert. I think maybe this was after as Washington was exceedingly hot & humid. At least the Coliseum was air-cooled. But I could be mistaken as to the timeline.

Wake of the Flood is the sixth studio album by the Grateful Dead. It was recorded between August 4 and September 1, 1973, and originally released on October 15, 1973. It was the first release under the band's own label, Grateful Dead Records, after fulfilling their contract with Warner Bros. Records. It was their first full-length studio album in nearly three years, since 1970's American Beauty. It was also the first studio album without Ron "Pigpen" McKernan, who had recently died. His absence and new piano player Keith Godchaux's tendency towards jazz (rather than McKernan's tendency towards the blues) changed the band's sound.^{[citation needed]}

This album has the only songwriting or vocal contribution from Keith Godchaux, "Let Me Sing Your Blues Away". This song was only performed live a handful of times,^{[citation needed]} in September 1973.

The album was released on Compact Disc first in 1995 by Grateful Dead Records and Arista before being remastered, expanded, and released as part of the Beyond Description (1973-1989) 12-CD box set in October 2004. The remastered version was then released separately on CD on March 7, 2006, by Rhino Records.^{[citation needed]}

Eyes of the World (Annotated)

 Right outside this lazy summer home
you don't have time to call your soul a critic, no
Right outside the lazy gate of winter's summer home
wondering where the nuthatch winters
Wings a mile long just carried the bird away

Wake up to find out
that you are the eyes of the World
but the heart has its beaches
its homeland and thoughts of its own
Wake now, discover that you
are the song that the morning brings
but the heart has its seasons
its evenings and songs of its own

There comes a redeemer
and he slowly too fades away
There follows a wagon behind him
that's loaded with clay
and the seeds that were silent
all burst into bloom and decay
The night comes so quiet
and it's close on the heels of the day

Wake up to find out
that you are the eyes of the world
but the heart has its beaches
its homeland and thoughts of its own
Wake now, discover that you
are the song that the morning brings
but the heart has its seasons
its evenings and songs of its own

Sometimes we live no
particular way but our own
Sometimes we visit your country
and live in your home
Sometimes we ride on your horses
Sometimes we walk alone
Sometimes the songs that we hear
are just songs of our own

Wake up to find out
that you are the eyes of the world
but the heart has its beaches
its homeland and thoughts of its own
Wake now, discover that you
are the song that the morning brings
but the heart has its seasons
its evenings and songs of its own

--song written by Jerry Garcia & Robert Hunter
