Nothing But Time by Jackson Browne & Howard Burke

From Running On Empty. Recorded "on a bus (a Continental Silver Eagle) somewhere in New Jersey" (9/8/77) while en route from Portland, Maine to their next gig in New Jersey. The bus's engine is audible in the background throughout, and its downshift and acceleration can be plainly heard during the bridge.

Rolling down 295 out of Portland, Maine
Still high from the people up there and feeling no pain
Gonna make it to New Jersey, gonna set it up and do it again
I got a bottle of wine (pass it over)
I got a broken white line (I'm still sober)
There ain't nothin but time between this Silver Eagle
And that New Jersey line
