J-Alex: because of misssing timestamps.
I havent got the time to look it up in the epi myself and search the exact song u mention (which can be pretty hard)
- Pink panther one is easy to recognise, look the epi once and write down the times
- "around 51:00" , the music during 51:00 has already been identified. so its to vague
- its very likely that there is more then one song used when they drove through "Woburn Safari park". so impossible to mention it in the first post.
nevertheless your identification is still valuable, if ppl look for music its possible that they get the title from ur post. Your contribution would be of even more value if u mentioned the start and stop time when the song is played.
