On Friday night, Taylor Swift fans watched Miss Swift take part in the "Stand Up To Cancer" telethon.  Swift, Tim McGraw and a handful of other musicians/singers performed in an effort to raise money and awareness.  Taylor performed a song called "Ronan", which she will now release."Ronan" is a song about a 4 year old boy who succumbed to the disease in 2011.  Swift penned the tune after reading the boy's mom's blog on the internet.  All of the money raised from the sales of "Ronan" will go to various cancer charities.  The song is available on iTunes, but you can check out the performance right here.....
