"LOVE IS A CIRCLE"©
By Manny Feldman
Love is a circle,warm as summer sun,
Making flowers blossom,after winter done.
Love is a circle,coming back to you,
When your love is given,with a hear that is true.
Love is a circle,going up then down,
Reaching to the heavens,returning to the ground.
Like a wheel that's turning a carousel of joy,
Love has a returning which only time can tell.
It may take a lifetime,an hour or a day,
But after love is given,love will find a way.
Love is a circle,take my hand my friend,
Love is a circle,love will never end.
Love is a circle,going round and round,
Reaching out to touch you,music all around.
Love is a circle,setting people free,
Love is a circle,love is you and me.
Love,once it is given,has no end,
Circling forever thru all time.
Bringing love wherever man may be,
Going on for all eternity.

Wedding anniversary wishes for a special couple –
Love is a rose,tender and pure;
Love is a tree,strong and secure,
Love is an ocean,
Love is for always,
Love is in all things”

Love is a rose but you better not pick it
It only grows when its on the vine.
A handful of thorns and youll know youve missed it
You lose your love when you say the word "mine".
I wanna see whats never been seen,
I wanna live that age old dream.
Come on,lads,we can go together
Lets take the best right now,
Take the best right now.
I wanna go to an old hoe-down
Long ago in a western town.
Pick me up cause my feet are draggin
Give me a lift and Ill hay your wagon.
Love is a rose but you better not pick it
It only grows when its on the vine.
A handful of thorns and youll know youve missed it
You lose your love when you say the word "mine".
Mine,mine.
Love is a rose,love is a rose.
Love is a rose,love is a rose.
