All-4-One的4个成员，是由加利福尼亚州土生土长的Tony Borowiak，Jamie Jones，Delious Kennedy和Alfred Navarez组成的。刚开始，他们发现自己该做什么并不困难，因为他们4人的声音配合得很完美。所有高科技声音合成，后期配音，都没法复制出他们那种独特的颤音和声。这使得人们发现还是有东西不能被仿造的。他们组队后不久，就推出了第一张单曲“So Much In Love”，人们开始注意了这4位杰出的男孩。这个组合就很快走红了。“So Much In Love”自从1994年1月发布后，马上攀上RIAA黄金销量榜，紧接着一曲深情的“I Swear”，直逼RIAA白金销量。这首歌不光成了1994年的年度最畅销单曲，还成了摇滚史上的第三个里程碑。同年4月，他们推出了同名专辑“I Swear”。接着，他们开始了全球巡回演出。在巴黎，马来西亚，新西兰，日本，韩国，他们突出的表现，使他们成为乐坛瞩目的组合。All-4-one在舞台上展现了他们最优秀的一面，他们以完美的声线和极富感染力的演唱技巧赢得了听众!

I swear
I swear
By the moon and the stars in the sky
and I swear
like the shadow that's by your side
I see the questions in your eyes
I know what's weighing on your mind
you can be sure i know my part
'cause I'll stand beside you through the years
you'll only cry those happy tears
and though I make mistakes
I'll never break your heart
and I swear
by the moon and the stars in the sky
I'll be there
I swear
like a shadow that's by your side
I'll be there
for better or worse
till death do us part
I'll love you with every beat of my heart
and I swear, wo..o...o
I'll give you every thing I can
I'll build your dreams with these two hands
we'll hang some memories on the walls
and when ( and when ) just the two of us are there
you won't have to ask if I still care
'cause as the time turns the page
my love won't age at all
and I swear
by the moon and the stars in the sky
I'll be there, i'll be there
I swear
like the shadow that's by your side
I'll be there, I'll be there
for better or worse, till death do us part
I'll love you with every beat of my heart
and I swear
( music )
I swear
by the moon and stars in the sky
I'll be there, i'll be there
I swear
like the shadow that's by your side
I'll be there, I'll be there
for better or worse
till death do us part
I'll love you with every beat of my heart
and I swear, I swear, oh I swear
