Lyrics:

In the 1970 film adaptation of the musical, the song is given to the character of Daisy (Barbra Streisand) instead of to her therapist, so the verse is cut and only the chorus is sung.
On a clear day
Rise and look around you
And you'll see who you are
On a clear day
How it will astound you
That the glow of your being
Outshines every star
You'll feel part of
Every mountain, sea and shore
You can hear from far and near
A world you've never, never heard before
And on a clear day
On that clear day
You can see forever
And ever
And ever
And ever more
