You're probably mixing up "addlive" with "Ad Lib." Which is the process of making something up as you go along. i.e. Fabolous said , "Don't get murdered over your song before ya ad lib it."
ad lib is short for ad libitum which means 'as desired", implying that the selection or topic is up to the desire of the speaker
Up as desired
To improvise; make up on the spot, sometimes in replacement of forgotten lines
The term is known as "Ad Lib" which means being spontaneous. The late actor Robin Williams was frequently asked to ad lib lines in movies throughout his lifetime. In the old TV show Mork & Mindy (with Pam Dawber) most all of his lines were spontaneous.
If you are asking if Shakespeare himself ad libbed you would get a resounding no. For Shakespeare was the author of the plays, the actors themselves would need to be the ones guilty of an ad lib. I do, however, understand the question is asking if, in fact, any of the Shakespearean actors ever used an ad lib. This would be impossible to factually. An ad lib is something added in to fill an entrance, exit or lengthy pause during a performance and even used to cover if a fellow actor messes up or forgets a line. Therefore there would be no proof anywhere to say whether or not this occurred. The only way to tell is to compare the performance to the script, since there were not recording devices (obviously) we could never know. I would like to believe Shakespearean actors did not ad lib. Since his work is written in a specific rhythm it would be frowned upon to ruin the flow of the piece and ad in things that were unnecessary. I have been involved with Romeo and Juliet recently and found that when an actor missed even the tiniest word in a line the entire flow of the scene would get disturbed. I could see how Shakespeare would greatly press onto his actors to say the lines verbatim.
His lungs were damaged and his doctor said not to sing.
New AnswerRemember the answer below is only an opinion. Nobody actually knows what the Doctor said. The producers have admitted that they will never let us know what the Doctor supposedly said to Rose and that it's up to the viewer to make up their own minds.Previous AnswerI think the Doctor said "I love you", that's why he left a double of him with her so they can be together

It depends on what they're acting in. If it's something like a 'classic' play - they'll usually be expected to stick to a script. If it's an improvised play, they'll normally be given 'free reign' to ad-lib - so long as they stay 'on subject'.
I don't know what ad you're referring to, each ad has a different song. Your best bet for finding it would be looking up the specific ad on Youtube. Once you find it, the song is probably a topic of discussion in the comment section.
