The Holmes show seems to have developed engine trouble and is struggling to make it back to the airfield..
One can usually tell how much of earner a show is for the TV station by the quality of the adverts - big budget beer and bank ads = lots of dollars. Ads for the local chippie produced in Powerpoint by the owners 12-year old = scraping the barrel. Prime tends to the latter..
