Muliple de 100 et de 6?

I think it's The Whale by Roger McGuinn and it may well have been on the album Cardiff Rose but I'm not sure. I know I have a copy of it somewhere here

that's a way of saying using slang: 'a [alcohol-fuelled] party for meeting again and parting again'

As-tu des oncles et des tantes means: 'do you have (any) uncles and aunts?'

des sourires et des embrassades = smiles and kisses vous : you

tu as des frères et des soeurs means 'do you have any brothers or sisters' - you can reply for instance: je n'ai ni frère ni soeur (I have neither brother nor sister) j'ai un (deux, trois, quatre)...
