  From a detailed study, including polarization dependence, of the normal state
angle-resolved photoemission spectra for Bi$_2$Sr$_2$CaCu$_2$O$_8$, we find
only one CuO$_2$ band related feature. All other spectral features can be
ascribed either to umklapps from the superlattice or to ``shadow bands''. Even
though the dispersion of the peaks looks like band theory, the lineshape is
anomalously broad and no evidence is found for bilayer splitting. We argue that
the ``dip feature'' in the spectrum below $T_c$ arises not from bilayer
splitting, but rather from many body effects.
