Wow, it's so fascinating to see all the variations. This is the way I learned it years ago at girl scout camp, though I've heard a few other verses since then. The first two are the same as others have already said here.

Rose, Rose, Rose, Rose
Will I ever see thee wed?
I will marry at thy will, sire
At thy will

Ding, dong, ding, dong
wedding bells on an April morn
Carve thy name on a moss covered stone
on a moss covered stone

Love, love, love, love
Gospel in a word is love
Love thy neighbor as thy sister
Love, love, love

Peace, peace, peace, peace
Wars will come and wars will cease
When we learn to live together
peace, peace, peace
