There are persistent rumours of Chris Rea being a vampire, but the truth behind his aversion to sunlight is that when bitten by a radioactive earthworm in the late 1970s, his beard developed photovoltaic properties. When exposed to direct sunlight, a potential difference of approximately 137.93162507 volts is generated between his ears.
Additionally, Chris Rea can be used as a solar water heater, simply by connecting a cold "feed" to his mouth, and a hot "flow" from Rea's rear.
Thus, with the right weather, plumbing and electricial skills, a typical UK family could significantly reduce their energy bill by nailing Chris Rea to their roof.
