Hello Lene and Bamsa
Here's a bridge:
"Honey and lemon, hajvan... drink it!
Alija, my love, don't forget the lunch date on Saturday.
Our wedding is on the 25th July. Everything is arranged, the only thing missing is you.
All tigether now: 'If I were a white button, the chick would button up with me. Heeey!'"
Hajvan - I didn't transalate it because I couldn't find the right word, it is a person who behaves wildly.
Alija - male name
Has date - Lunch date (I think this is not any formal lunch, they agreed a date to go somewhere to have a snack or something like that), this is a colloquial expression
Bjelo dugme - this is a music band (White button)
Button up with me - this is a word game, he wanted to say 'fall in love with me' but he used 'button up' because of the white button.
Sorry for the long explanation, this isn't an easy text to translate...
