Margaret for my wedding song

I get married in May and I am 99% sure I want to have Margaret as my walking down the aisle song. Margaret is my middle name/a family name and the song has meaning to my future husband and I so seems perfect for that reason.

I just need some opinions/expertise - do I keep it as the raw song with lyrics or do an instrumental version? Or are there any versions online that people would recommend?

Many thanks :)
