Get on the [bad word] while you can

Get on the [bad word] while you can
The Cosmo-train is a word-express
Get on the Cosmo-train

The night is night and day is day
and black is blackness every way

Get on the Cosmo-train
It's darker than the night
Eyes that see always the light 
is not accostumed to the night
for night is night and day is day
and light is light

but rays of light are sometimes dark
and lights of dark are sometimes black

the schedule speaks to Cosmo Man
get on the [bad word] while you can
