From the Super Simple Songs collection, this one has a verse (in English) to celebrate a child's birthday. There's also a yom huledet sameach verse. And the song wishes the child not only a happy day but also a happy year ahead. But there are other verses to choose from as well, depending on whether you're celebrating the birthday of the world (Rosh Hashanah), of the trees (Tu B'shevat), of Israel (Yom Ha'atzmaut). The song's range is just 5 notes. Easy peasy.
