I managed to get a stalls ticket for the Thursday night at the King's.
I saw him last year doing Snowflake/Tornado having seen the embryonic Tornado at the Fringe 4 years ago.
Have also seen "If You'd Prefer a Milder Comedian" (the Top Gear diatribe) at the Leicester Square Theatre, "Carpet Remnant World" and "Content Provider" at The Assembly Rooms, and a WIP for his Comedy Vehicle at The Stand in Edinburgh.
