"Why Does the Sun Shine?" is a funny song on the solar physics originally written by Singer and Zaret.
Here it is covered by They Might Be Giants, an alternative band from
the 80's, best know for their super-mega-hit "Istanbul (Not
Constantinople)". On the same album of children's music TMBG published
another song - "Why Does the Sun Really Shine?", an errata to the
original one ("the Sun is miasma of incandescent plasma" :) ). Both songs can be heard on YouTube:
