What is the name of the song played for Going Merry's funeral? What is the name of the song played for Going Merry's funeral?

I have heard that is a large version of an ending but i do not know if it's true or not.

The number of the episode is 312 and also in the episode of Merry's OVA.
I believe the song you are looking for is either 'Dear friends' 

One other option could be 'Mother Sea'.
