In the 2017 show, As Yet Untitled (here) Jimmy had spoken about doing a June 2016 promo for Jaguar, where he had to surprise Andy Murray by turning up to be his chauffeur. Taking him to Wimbledon for his 2^nd round match.

The Jaguar archive article says:

An early alarm call from the world class stand‑up, who swapped the stage on his sell‑out tour for a role as Jaguar’s Secret Chauffeur, stunned the 2013 Wimbledon Champion outside of his home in an All‑New Jaguar F‑PACE. Murray’s support team and Jaguar had called upon Carr as part of a fun, practical joke on the Scot as he attempts to win his second Wimbledon title.

The pair discuss yummy mummies, Ivan Lendl’s paunch, and the art of grunting whilst Carr offers some tactical advice on how Andy could put off his opponents.
