But the 37 year old wasnâ€™t prepared for what was to follow at the London Palladium.
From being chucked out of a dressing room by Bette Midler, helping Russell Kane find his shoes, performing in front of a bear chested Simon Cowell and hearing about Prince Williamâ€™s rugby banter, the comic was left feeling pretty overcome by the whole affair.
â€œIt was undoubtedly the biggest gig of my life so far,â€ he said â€œand one of the most incredible nights of my life.
â€œBut surreal, from the moment we left the house to the moment we got home.
â€œI was the only one on the bill Iâ€™d never heard of.â€
Broadcast on Monday night, this yearâ€™s eclectic mix of acts, including the likes of Dame Shirley Bassey and Ellie Goulding were watched by the Duke and Duchess of Cambridge.
For Rod though the real entertainment happened backstage.
He said: â€œI was sharing a big dressing room with all the comedians, Jack Whitehall, Russell Kane and a comic called Trevor Noah when it became clear that someone had overlooked the fact that Bette Midler might need the toilet.
â€œTheyâ€™d put her in a small room next to the stage and she was not best pleased so they swapped us and squeezed four comedians into this tiny room.
â€œThe next thing Russell Kane, who is getting ready to go on looks down and canâ€™t find his shoes.
â€œSo weâ€™re all turning the place upside down looking for these shows when Trevor Noah comes off the stage wearing them. The wrong size, different colour, orthopaedic inserts.
â€œThatâ€™s how nervous you are going on. You donâ€™t even know if you have your own shoes on.
â€œThe intensity is really strange.â€
He added: â€œThen when I was on stage there was only one person I could make out.
â€œEvery single person was in black tie except, at the epicentre of everything, with his shirt open to his belly button was Simon Cowell, so I was standing there expecting him to buzz me off at any point.â€
But the most memorable moment of all came during the royal lineup.
â€œI knew William and Kate had been down in Wales recently watching the rugby and had been entertained by Dennis Gethin who is president of the WRU and also a good pal of mine,â€ he said.
â€œSo I said to William that Iâ€™d seen him at the match with Dennis and he went off on one.
â€œHe said â€˜I absolutely love winding him up, ask him about me ribbing him at the rugbyâ€™.
â€œSo I call Dennis afterwards and he said â€˜yeah he was winding me upâ€™.
â€œIt turns out they were watching the game and Dennis turns to William and tells him to look at the physique of the number 20, who is built like a brick-proverbial.
â€œSo William turns to Dennis Gethinâ€™s wife and says â€˜Jan Iâ€™m a bit worried about your Dennis, heâ€™s taken a real fancy to the number 20â€™.
â€œLike I say, all it was a fairly strange night.â€
Rodâ€™s venture into comedy began around 15 years ago, while performing with the Young Variety Club in Cardiff.
It was there his first big break came, after being spotted by legendary Welsh TV presenter Arfon Haines Davies.
â€œHe asked me to come down and work for HTV as a warm-up man at the studios in Culverhouse Cross, â€œ Rod said.
â€œBefore that point I was looking to go to uni, maybe following my dad into sports journalism, having been told there was no job in comedy.
â€œHaving said that when I told my careers advisor I wanted to do just that at the age of 14 he wet himself laughing, so I thought I was on to a good thing.
â€œI ended up taking a year out from University and ended up doing stand-up.
â€œI took my act to Edinburgh and entered a competition called So You Think Youâ€™re Funny, which was won that year by Peter Kay, and I started to learn from there, how to play the clubs, deal with the difficult audiences and so on.
â€œBut there was no tougher audience than the HTV crowd, working on shows like Telephonin and Moon and Stars, because the weird thing was that the same people would turn up week in week out.
â€œYou suddenly realised you had no act left because you were on first name terms with the audience.â€
Having completed runs in Edinburgh and most of Londonâ€™s Comedy Clubs Rod entered a competition called Funny Business on BBC Wales three years ago, which he won.
Since then his focus has been on making the breakthrough to national television, which eventually came after a gig in Liverpoolâ€™s Cavern Club.
â€œSome people from ITV came up to see me on that bill and next thing I was told I was being considered for a TV show, not knowing it was the Royal Variety.â€
He added: â€œIâ€™m hoping on the back of this to put together a little local tour.
â€œWeâ€™re finalising the venues now so look out for that in the new year
â€œFrom the reaction at the Royal Variety Iâ€™m hoping this is the start of bigger things.â€
