Rock music on 87.7 in Romford area. Seems to pop up every now and then, especially over holiday periods.

Stereo? Could be "Cruisin' Radio". That sometimes appears at holiday times in East Anglia or on the South Coast.

It's that RTL Rock Radio thing again. Back to back classic rock using the now defunct Dutch stations jingles. Very low power as it seems to radiate only a few miles. The audio quality is superb though.
