Graduation Day lyrics

Right now we'd like to do another song about school
We did it last time I think
This one's dedicated to everyone in the audience who's just graduated from grade school
And all you who have just graduated from junior high or high, or high school
That is if you happen to make it out of high school, yeah
If you haven't there's always hair school, I mean night school
Summer school? I went ther for two semesters, you don't have to tell me about that
Anyway right now we'd like to do the song that was recorded several years ago by a group of of singers
Who were very influential for our careers because they influenced Brian Wilson and his writing
Their group is the Four Freshmen
And their song that we'd like to sing right now is called "Graduation Day"

There's a time a for joy
A time for tears
A time we'll treasure through the years
We'll remember always
Graduation day

At the senior prom
We danced 'til three
And there you gave your heart to me
We'll remember always
Graduation day

Take it away
Take five

Though we leave in sorrow
All the joys we've known
We can face tomorrow
Knowing we'll never walk alone

When the ivy walks
Are far behind
No matter where our paths may wind
We'll remember always
Graduation day

We'll remember always
Graduation (day) day
