I'm not sure which 'leaving' you mean. I've been ready to go for some time now, ...
... But when I leave I want to go out like Elijah
With a whirlwind to fuel my chariot of fire
And when I look back on the stars
Well, It'll be like a candlelight in Central Park
And it won't break my heart to say goodbye
(I think Rich Mullins' understanding of Heaven is still now better than what I have ever grasped.)
"When I look back on the stars, it'll be like a candlelight in Central Park"
The mental image of leaving this earth, this solar system, this galaxy of a billion solar systems, of leaving this universe of a billion galaxies; on and out to the point where the stars are like a lot of candles in central park viewed from a distance, and to the point where the distance is so great the candles just look like a single light source ...
and still, you're not even close to how far Heaven is from earth.
I'm going to answer your question as a single note instrument (tenor sax) player and give examples of progressions I love to play over, sans video for the same reason as Bruce above. There are quite a few worship songs we do that I'm given freedom to play over the chord progression either as a main solo or in conjunction with other lead instruments (lead guitar/keyboard) and my favorites are:
Revelation Song (Jennie Lee Riddle)--D Am C G --same progression throughout the song--This has worked remarkably well with just an acoustic guitar, keyboard, and sax and works even better with more instruments to fill it in. I love coming in at the end of the chorus with a high D (E on tenor) for the 1st measure and working my way down the horn 2 octaves by the end of the progression and 'handing it off' to the singer for the next verse.
Highest Place (Ramon Pink)--a 12 bar song with a very similar progression to a classic 12 bar blues.
4 measures of D,--
1 measure of G, 1 measure of A for 2 beats and G for 2 beats, 2 measures of D, --
1 measure of Em7, 1 measure of A7, 1 measure of G, 1 measure of D
I spent my formative improvisation time playing over blues progressions and love 12 bar progressions as a result. I've found very few in worship songs and we've resurrected this 1983 out of retirement just recently.
As Children (Jeremy Riddle) 6/8 time with the basic verse being 4 sets of '
GSus for a measure, G for a measure, D for 2 measures
It's a very powerful and meaningful tune for a struggling church that's been through the ringer the past couple years and has been received very well. I love 6/8 time and the simple progression makes it easy to build a nice solo for the 6x we go through it with instruments only to end the song.
My Redeemer Lives (Reuben Morgan)--I love the opening progression of E7, A7, E7, A7 etc. It's simple and you can add blue notes for flavoring, which don't work in many worship songs.
Not sure if this is what you were looking for in an answer, but it's the best answer I have.
