After talking to a few other parent friends of mine, we found out that "1,2,3,4" is not only a hit but, basically a wonderful children's song (only, she doesn't count right when she's singing, as Mags has noted)
Magnolia once told me to tell Leslie Feist that she should name her guitar "Singy" after Feist announced from the stage that her guitar is nameless. Mags was so into the concert that she's been singing her songs ever since that show (last summer, pre-ipod commercial).
PS: Since Jason and I both went to KU, I watched a basketball game last night and it was so good I wanted to move back to Lawrence.
