Early on Neill made a speciality of Scottish Highlands-themed strips, such as The McTickles and its successor Wee Ben Nevis, a male Pansy Potter. He drew Plug's own strip in the eponynous comic in the late seventies and subsequently in the Beezer.
During this period he was also drawing many strips for IPC magazines (details at Toonhound). In the eighties he took over The Germs from David Sutherland, and drew Billy Whizz for most of the nineties. His most recent success has been Tim Traveller, the boy with the time-travelling bike (and obligatory bizarre hairstyle).
