Pink Floyd guitarist David Gilmour is back with a new solo album and six-night residency at London's Royal Albert Hall, and it's probably fair to say that we've been here before. In 2016 he released Rattle That Lock, and played half a dozen shows at the same venue at the end of a tour to promote the album. As it was released, we boarded Gilmour's houseboat on the River Thames, where he told us about his 50 years with Pink Floyd.
