Terrapin Station

The song mentioned by Scott Bairstow's character thematically ties into the film and reflects what Will is going through

Grateful Dead - Terrapin Station

Inspiration, move me brightly
light the song with sense and color,
hold away despair
More than this I will not ask
faced with mysteries dark and vast
statements just seem vain at last
some rise, some fall, some climb
to get to Terrapin

Counting stars by candlelight
all are dim but one is bright:
the spiral light of Venus
rising first and shining best,
From the northwest corner
of a brand-new crescent moon
crickets and cicadas sing
a rare and different tune

Terrapin Station
in the shadow of the moon
Terrapin Station
and I know we'll be there soon

Terrapin - I can't figure out
Terrapin - if it's an end or the beginning
Terrapin - but the train's got its brakes on
and the whistle is screaming: Terrapin
