Still a german wedding anniversary is coming up

Still this coming sunday , Hagen and Nylka , our great german neighbours in Errislanan will celebrate their 30th anniversary and they seem truly happy .Bravo to them ! This is her song on face book :

Im gonna love you like nobodys loved you come rain or come shine
High as a mountain deep as a river come rain or come shine
I guess when you met me it was just one of those things
But dont ever bet me cause Im gonna be true if you let me

Youre gonna love me like nobodys loved me come rain or come shine
Happy together unhappy together and wont it be fine?
Days may be cloudy or sunny
Were in or were out of the money.
