That’s pretty cool. 
Wonderful!. Thanks from here too !
It’s very true that your first Doctor is your best Doctor. Showing my age here, but for me these were Patrick Troughton and Jon Pertwee. I still remember the episode where the Second Doctor is being given a choice of bodies by the Time Lords for his exile on Earth, and he rejects each one for various reasons : too fat, too ugly, too bald, etc. Ultimately the Time Lords get pissed off and force the Pertwee face on him willy nilly, to loud protests. The next shot shows Pertwee emerging out of the Tardis and collapsing onto a green English field.
I was young enough to find the change to Tom Baker after a long series of Pertwee disturbing, and I only saw the transformation episode of the Fourth Doctor before leaving televisionland. I’ve missed all the intervening Doctors, but thanks to satellite TV have been able to see Nine and Ten, who are magnificent, in my opinion.
The music seems to have changed little. Thrills me the same as so many years before, and I have to wait for it to finish before switching channels. Good riddance to the electric guitar though.
I watched a lot of Tom Baker in my youth and so he always seemed the iconic one to me (yeah, just like about everyone else). I really liked Eccelson and thought his tenure was the too short but I liked Tennant’s Doctor better. We’ll see how Matt Smith does, he seems awfully young in the pictures I’ve seen.
And interestingly enough, I don’t get to listen to the theme too much when I watch the show. I mute it because my 2 year old son as well as my 7 year old daughter go bonkers for it.
Bah! All you youngsters can get off my lawn. 
Having watched the first episode live 
(and everything since), I am positive that David Tennant has displaced **Tom Baker **from top spot.
I guess my first Doctors were Nos. 2, 3, and 5 (as in “The Five Doctors,” minus No. 1 who was portrayed by a stand-in and No. 4 who was trapped in a time vortex or something through the whole adventure). I’ve seen every episode of the new series and only a few episodes here and there of the previous doctors but, for reasons I can’t quite explain, I’m particularly fond of William Hartnell (the real First Doctor). Yes, he had trouble remembering his lines, was limited in his ability to dash around in corridors and quarries, and didn’t display the emotional range of the most recent Doctors, but for some reason I’m charmed by the grumpy old coot.
Similarly, I like the version of the theme that was used in those early serials. Yes, the primitive electronic score says “vintage sci-fi cheese” to modern ears, but it also has a spooky, eerie quality I find totally lacking in the '80s disco or '00s orchestral versions. My appreciation for it was enhanced by reading about how it was produced with no computers or synthesizers, basically spliced together note by note.
