an idiom

[yuftos]

hi,
I couldn't find the meaning of thi idiom:''run-on piece of mount on''
can you tell me what it means?
and I have a problem on the usage of ''open'',''close'';
-we are open....
-we are closed...(we are close=we are good friends)
but
-does the bar open...?-I opens...
-does the bar close...?-It closes...
-Is the bar open/close....?-It is open/close
They are all confusing!!!why do we use....?where do we use all of them?
Thanks a lot:)

[Tdol]

We are open/ we are closed (adjective)
What time do you open/close (verb)
Is the bar open.closed (adjective)

Is the bar close = is the bar near here

I don't know the phrase 'run-on piece of mount on''; can you supply the context?

[yuftos]

''And all the Spanish candles unsold
Have gone away to this
And a "run-on piece of mount on"
Trembles, shivers runs down the freeway
I guess she spent her last quarter randomly''

-It's in the song of tindersticks named ''here''
what can it mean?
