  We consider the extension of the standard model with an arbitrary number of
U(1) gauge fields coupled to baryon-minus-lepton number and/or hypercharge.
Under the assumption that A^b_FB from the LEP1 experiment is an unlucky
fluctuation, we find moderate evidence for the presence of such fields in the
precision electroweak data. A relatively large range of the Higgs boson mass is
allowed. We discuss the phenomenology of the extra U(1) fields.
