Need help identifying a song

[newdanfan]

I've just became a fan of Daniel Johnston's music after watching the documentary. There is one song that really gets my attention though and I am trying to figure out the name of the track. The song plays in a few of the trailers and is just Daniel playing the piano. The song is very slow seems to be just him singing and playing the same cords on the piano over and over again. Can someone please help? Thanks.

is this the song you're referring to..?..

i was guilt stricken
to go away
she turned w/out saying
i could not stay
and all the while
she was smiling at me
like i was a show
on her tv

people have asked about this one before
but no one seems to know what it is. 
i love it.

or are you talking about the song heard in the background
throughout the film

'some things last a long time'  ?

opening lyrics:   your picture / is still / on my wall ..
