There have been many groups to record this song. The Ambassadors recorded this many years ago when the man that wrote it sang with them
Mr Jack Campbell passed away last year.

What is the name of the group that sang this? Please help!

"OH WHAT A HAPPY DAY"
VERSE: 1

OH WHAT A HAPPY TIME THAT'S SURE TO BE
WHEN MY JESUS IS COMING AFTER ME
I HEAR HIM CALLING ME AWAY, FROM THIS OL' WORLD
FOREVER TO STAY
AND WHEN I TAKE MY SAVIOR'S HAND, IN THAT BLESSED
PROMISED LAND
I'LL SHOUT AND SING THROUGH THE ENDLESS AGES
OH WHAT A HAPPY DAY------!!!

CHORUS:

OH WHAT A HAPPY DAY--------------THAT WILL BE WHEN WE GATHER THERE
WHAT A HAPPY DAY

THERE, OH WHAT A HAPPY DAY WHEN WE
WHAT A HAPPY DAY

CLIMB THOSE GOLDEN STAIRS, WE'LL MEET WITH THOSE WHO HAVE GONE BEFORE JAMES AND JOHN AND A MILLION MORE, WHAT A HAPPY
TIME THAT'S SURE TO BE, OH WHAT A HAPPY DAY
WHAT A HAPPY DAY

VERSE: 2

AND WHEN I WALK INTO HEAVEN FAIR, I'LL SEE MY BLESSED SAVIOR THERE, HE'LL PLACE A CROWN UPON MY HEAD, GIVE MW A ROBE OF WHITE TO WEAR, I'LL WALK ON STREETS OF PUREST GOLD
I'LL LIVE FOREVER AND NOT GROW OLD
I'LL SHOUT AND SING THROUGH THE ENDLESS AGES,
OH WHAT A HAPPY DAY-------

WORDS AND MUSIC BY MR. JACK CAMPBELL

What A Happy Day

Cho.
What a happy day that will be when we get up there
What a happy day when we climb those golden stairs
I'll meet the ones who've gone before James and John and a million more
What a happy time that's sure to be what a happy day

Don't know all the words to the verses.

Do you know somebody the lyrics this song?

Oh what a happy day that should to be,
Jesus coming after me
I hear Him calling me away
from this old world...
And when I take my Savior's hand
In that blessed promise land ...

Ref:
Oh what a happy day that'll be when we get up there
Oh what a happy day when we claim those golden stairs,
I meet with those... gone before ...
