The singer, whose band split in December (13) after a farewell tour, is setting up his own deer farm in Scotland, and is thrilled the British royal has got people talking about agriculture after starting a 10-week course on farm management earlier this month (Jan14).
He tells Hello! magazine, "I think it's fantastic that he's doing this and that it's brought a new focus to the farming industry. I've met Prince William and he's a cool guy. Anything that gets young people interested in farming and rural communities is a positive thing."
And Gill is keen to follow in the future monarch's footsteps and sign up for similar study sessions.
He adds, "That's exactly the kind of course I want to go on but that one is bespoke - it has been tailor-made for Prince William. Although, who knows, maybe if he reads that I want to do it, they can call me up and we can study together? That would be wicked."
