When Ealing's little comedy club lands its coup of the year and lands a bona fide comedy star, resident comic and promoter of Downstairs at the Drayton, Phil Zimmerman, could be forgiven some well deserved blowing of the proverbial trumpet.
Likewise, some nervous pacing as the moment of truth arrived and your man is not even in the building - apparently because The Avenue is not on his comedy map.
It's something of a relief then, when Harry Hill finally peers Eric Morcombe-like around the entrance to the club in a flat cap before finally making it onstage - fashionably later than planned.
Dressed in his trademark outsized collar and suit and starts pointing out fellow baldheads and launches into a typically surreal show that finds the real life doctor in slightly darker territory than mainstream shows like TV Burp and You've Been Framed allow.
Gary Hill gets an airing for a bit of ventriloquism, religion comes under the spotlight, and a long winded story of how people who leave the washing machine on standby are animal murderers is an extreme tangent and Hill in one of his best flights of fancy.
The mixed crowd enjoys a rare and small performance from a unique performer but the real star of the night is the evening itself, which started three years earlier in the Drayton, upstairs playing to one man and his humourless dog.
And although Downstairs pulls in a consistently high standard of acts, and is set to go fortnightly and even weekly soon, Harry Hill is probably the biggest name yet at the pub, which seats less than 100 people.
When telling people I was going to see him, I was consistently asked, 'what, in there? I thought he would be playing in theatre.' So hats off to Phil, whose inner Sat Nav paid off when he guided his star to the gig on Friday night.
"We were bombarded with requests for tickets for this show and could have sold it five times over, " he said.
"It was a really memorable night for the lucky few who managed to get tickets.
"Harry had trouble finding the venue because he said the avenue wasn't on his map. Well after Friday it's definitely on the map now.
The next show is on October 3 and features Iranian comic Shappi Khorsandi, returning after a sell-out appearance at the Drayton in March. Tickets are available now by credit card at www.wegottickets.com
