Sir, – Further to “U2 live in Las Vegas: An unforgettable gig unlike any other” (Music, October 2nd), am I taking a gamble on an ironic dad joke about the four environmental campaigners who did a residency in Las Vegas which is ranked by climatecheck.com as the most drought-risk city in the US?
Or do emissions created in Vegas stay in Vegas? – Yours, etc,
NIALL McMANUS,
