Lee Dorsey: Ya Ya
This song is so infectious and fun, it's hard not to love. America agreed by making it a number 1 hit in 1962.
In the song, which was apparently inspired by a nursery rhyme, but for the life of me I couldn't tell you which, seems to be referring to a lover as Ya Ya. He's "sitting in La La waiting for my Ya Ya". Regardless, the song is clear, he wants her to hurry up and get to where he is.
