Reruns of TBBT on British TV tend to leap in and out of series and season order. I'm pretty sure the theme tune has been re-recorded at least twice as a season one version sounds subtly different to one from season fou,r and again from season seven. it's subtle and nothing big gets changed, and you'd never notice if watching shows in chronological order - but it's definitely happened.
