Best, Rottgering & Lehnert (BRL) defined a new sample of powerful radio sources from the Molonglo Reference Catalogue, for which redshifts were compiled or measured for 177 of the 178 objects. For the final object, MRC1059-010 (3C 249), the host galaxy is identified here using near-infrared imaging, and the redshift is determined from Very Large Telescope (VLT) spectroscopy. For one other object in the sample, MRC0320 + 053 (4C05.14), the literature redshift has been questioned: new spectroscopic observations of this object are presented, deriving a corrected redshift. With these two results, the spectroscopic completeness of this sample is now 100 per cent.
New redshifts are also presented for PKS0742 + 10 from the Wall & Peacock 2.7-GHz catalogue, and for PKS1336 + 003 from the Parkes Selected Regions. PKS0742 + 10 shows a strong neutral hydrogen absorption feature in its Lyman alpha emission profile.
