Ok i can reveal it to you where my nick came from...

It was years ago while i was working in South America ( French Guyana ).
As usual, Job mates & me after work relaxing ourselves by a nice drink ( Rum, sugar and green lemon) contemplating the ocean in saying : ' Life isn't beautiful ? ' and most of us answered :' Yeah ... i say yeah ... life is so cool '

I took the ' I say yeah ' and transformed it by 'Asayyeah' ( phonetically close in french from the english 'i say yeah' ) and from that time i used it like my own anthem for life
