Every shalala every wo‘wo still shines. Every shing-a-ling-a-ling that they‘re starting to sing so fine When they get to the part where he‘s breaking her heart It can really make me cry just like before. It‘s yesterday once more. (Shoobie do lang lang) (Shoobie do lang lang) Looking bak on how it was in years gone by And the good times that had makes today seem rather sad, So much has changed. It was songs of love that I would sing to them And I‘d memorise each word. Those old melodies still sound so good to me As they melt the years away Every shalala every wo‘wo still shines Every shing-a-ling-a-ling that they‘re startingTo sing so fine All my best memorise come back clearly to me Some can even make me cry just like before. It‘s yesterday once more. (Shoobie do lang lang) Every shalala every wo‘wo still shines. Every shing-a-ling-a-ling that they‘re starting to sing so fine Every shalala every wo‘wo still shines. Every shing-a-ling-a-ling that they‘re starting to sing‘‘‘
