Supernatural

Co-showrunner Andrew Dabb revealed that COVID meant the writers had to rework the final two episodes of the series. Dabb said: 

Dean was always going to end up in Heaven, and we were always going to see Sam's life in fast-forward, but those final moments were supposed to take place somewhere else. When Bob Singer and I sat down to talk about season 15, and our inevitable end, we came up with something that felt like a fitting version of Sam and Dean's Heaven: all the people the boys had met along the way (or, at least, those we could convince to fly to Vancouver) crowded into a re-built Roadhouse, as the band Kansas played our (official unofficial) theme song: 'Carry on Wayward Son.'
