Just got it! #47(1) is Anarchy in the UK, by the Sex Pistols.
Correct.
Not quite- Surfin’ Bird, by the Trashmen. 
Paul and Linda Mc Cartney, regarding Bloody Sunday.
Think both of these remain unanswered…
It’s Janis, singin “Me and Bobby McGee” for the first one.
Correct. Well, ok, Kristopherson wrote it. But Janis is responsible for the definitive cover.
The second is “Free Bird,” I think.
A) There is but one young human male who I might be expected to have strong feelings for me; he is the progeny of an adult male who spreads the word of a deity.
B) An unkind adult male who shares the moniker of a common table condiment takes his rest in the pastoral recreational area, removes his whiskers without benefit of light in an effort to conserve a material fashioned from cellulose pulp.
C) Negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, negative, there is no other person who has the ability to move their body rhythmically in a very specific manner in response to music in a fashion similar to my own.

#69c: Pretty sure it’s this one. 
Nobody’s guessed mine yet…was it too obvious?
Correct. Sadly, not aka “Oak’s Anthem”, but it really should be.
(a) Would anyone care to divulge which of you released the pooches? Which of you?
(b) Large-scale armed conflict… now then, let us consider the benefits of it. In my opinion, they are few. This bears repeating.
I beg of you, tiny infant, please do not assume all is lost!
I insist that you not prevaricate, lest that which is incorrect appear to be without fault.
That which is to be cannot be contained between a single sunset and sunrise.
It is inscribed in the light diffusely reflected by the earth’s only natural satellite!
Applied with pigment to celestial blobs of plasma…♪
I like what you did there. 
Heaven & Hell, Black Sabbath!
Nobody has answered my first one (69A)
mmm
Taking a load off atop the surface of a resting device built to accommodate more than a single person in a pastoral setting,

A) My conflagration is diurnal, my conflagration is nocturnal. Physical resistance appears to be pointless, as I am indebted to a cartoon character appearing on a tin of spicy pork. My conflagration is thine.
B) I’m becoming a traffic circle.
C) Were I to loiter in sync with Earth’s passage, as you presume, your reasoning is inherently flawed due to the fact that it’s a dog eat dog world. Beyond the horizon lies great treasure which yearns to be possessed by someone, anyone; and if you continue to presume that I will loiter in sync with Earth’s passage, your reasoning is not only inherently flawed but also utterly insane. Karma will prevail.
