Abstract: A portion of a sample of 4C radio sources selected for their ultra-steep radio spectrum has been identified. Most are at high redshift, including the most distant galaxy known, 4C41.17 at z = 3.8. The extended optical/infrared continuum of high redshift radio galaxies is generally aligned along the radio axis. The spectral energy distributions can be nearly flat in the rest frame ultraviolet, but rise significantly into the red. While the nature of the optical/infrared continuum is controversial, it is likely that aligned radio galaxies are dominated by starlight, and that at early epochs powerful radio sources were capable of stimulating vast amounts of star formation.
