During filming, Tim Healy injured his eye by catching it on the page of a magazine he was reading, leaving it very sore and swollen. This is very evident in the scene where Neville confronts Dennis over the terms of his relationship with Ally Fraser.
This episode continues a running cowboy theme in the series, which includes the lads dubbing themselves the Magnificent Seven early on, and comes to a head in this episode, which includes Midlands Cowboys, and a cowboy plumber called Harry Blackburn.
In joke: Oz tells Harry Blackburn that the worst thing about his time in the Falklands was the Jim Davidson visits. Joe Fagin who sings the theme tunes on series one and two, was actually Jim Davidson's tour manager on his visits to the Falkland Islands.
Oz's singing abilities at the country and western night were no doubt a bit of a shock when this episode first aired, and Nail was an unknown. However, Jimmy Nail went on to have quite a successful musical career after series 2 of Auf Wiedersehen Pet. His Crocodile Shoes album of 1994 sold over a million copies, mainly in the UK. Nail has also recorded with Gary Moore, David Gilmour, Mark Knopfler and George Harrison. His music has also received Golden Globe and Ivor Novello nominations.
Barry mentions that he understands ghosts, because he played the Banquo Kid in a workshop Western production at Walsall Tech. In the play Macbeth, both Banquo and Macbeth are Scottish generals, who meet the three witches. The witches prophesy that Macbeth will become King of Scots, but that Banquo's children will become kings. Because of this prophecy, Macbeth has Banquo murdered, and Banquo's ghost comes back to haunt him (as Barry says). There is also a traditional stage superstition that the play's name should not be used, so many actors refer to it as the "Scottish Play".
There is some argument as to how Shakespeare would have spoken. Barry and Wayne's suggestion that he had a Brummie (Birmingham) type accent has some supporters, while others suggested he would have sounded more rural, like someone from the Cotswolds. One thing is fairly certain however, he would not have had the posh accent that he has been given in many films.
Cowboys is the culmination of all the western references in series 2. Earlier on, the lads have compared themselves to the Magnificent Seven and the Wild Bunch; Oz has said that he went to Nashville, Memphis and Texas (and met someone claiming to be Merle Haggard) and Dennis has complained to Howard Radcliff that the lads do not want to do a cowboy job. In Cowboys, the lads attend a country and western night, Oz sings a country song, they meet a real cowboy plumber, and have a western-style stand down at the end. Andalucia, where some of series 2's action takes place was also the location where a number of the so called spaghetti westerns were filmed.
Bomber says that he prefers Adge Cutler and the Wurzels, and West Country Music. The Wurzels came from Somerset, near Bristol, and styled their music Scrumpy and Western after the type of cider. Drink up thy Zider (in West Country Dialect) was released in 1966, and is practically regarded as the "national anthem" of North Somerset and Bristol, if not all of Somerset. It is by far the most famous Adge Cutler song, often played on local radio. It is also the anthem of Bristol City F.C.
Spain entered the Common Market (EEC) in January 1986. Soon after many denizens of the so called Costa del Crime, either moved away or were extradited. The heyday of the Costa Del Crime was between the late seventies, and mid eighties.
It is perhaps surprising that Oz, and not Wayne (Gary Holton) had a chance to sing in Auf Wiedersehen Pet. Holton appeared as lead singer of several real life bands, such as the Heavy Metal Kids. He was also the lead singer of the Damned during their 1978 Scottish tour, and was considered as a replacement for Bon Scott as lead singer of AC/DC after he died in 1980.
