No. In songs and in poems, sometimes improper grammar is used but it is understood to be used in a poetic way, not exactly a grammatically correct way. I think "love me do" is from a song.
"We performers love correct grammar" is better!
in the celebration of love of a life time
heart should be hearts
I would have loved to meet your friend.
The correct grammar for this sentence is: When did your friend come?
no_____If the sentence is You do do that (meaning You are in the habit of doing that) the grammar is perfectly correct and the sentence 'does have correct grammar'.
"We performers love correct grammar" is better!
It is not actually a sentence. It is a complete subject with no predicate. A sentence would be "This is an example of what love is supposed to be."
in the celebration of love of a life time
heart should be hearts
That sentence is grammatically correct.
No.
The correct grammar is "Between you and me."
"Roger and I appreciate what you did" is correct grammar
The grammar in the question is correct.
I would have loved to meet your friend.
Yes. What is not correct is your putting the article "a" before grammar.
