I’m the songs in a show; I help painters prosaic;
The mob’s betting racket; the fourth book Mosaic;
The terms’ coefficients in strings algebraic;
And Apple’s own app for all things formulaic.

Who am I?

I’m the stalk of the grass that the sugar men pick;
I’m an athlete from Raleigh who scores a hat trick;
I’m a Singapore sentence; a curved walking stick;
And a mint-flavored candy you’d get from St. Nick.

Who am I?

I’m the musical Rose of whom Fanny Brice sung;
I’m the smoke from another that reaches your lung;
I’m bought formerly owned; I’m a tale spread by tongue;
And just give me a minute, and I’m fully swung.

Who am I?

I’m a station you’re changing when less than engrossed;
Found between mainland France and the low English coast;
I’m a YouTube account where a user can post;
And I’m using your body for hosting a ghost!

Who am I?

I am pioneer film, and I’m vintage TV;
A sedan that identifies LAPD;
Three Dog Night’s number one from their “Seven” LP;
And the cookie that hopes to unite NYC.

Who am I?

I’m the rate that investments will cost or expend;
When a once absent Jedi shows up to defend;
I’m a form for your taxes; give back what they lend;
And a typewriter key used when reaching the end.

Who am I?

I’m a walk for your health you might push to extremes;
I’m foundational-document-driven regimes;
I’m a stiff morning drink that does more than it seems;
And a law that’s been cleared by the DC Supremes.

Who am I?

I’m a serving of wine, or a tall pint of beer;
In the church I am stained, but in banks I am clear;
I am Google’s computer that sits on your ear;
And a clever composer, intriguing to hear.

Who am I?

UPDATE: Riddle solved by Asher. See comments for answer.

I’m a small brood of chickens; the eggs in a hatch;
I’m to grasp a hold tightly; to greedily snatch;
A third pedal in cars, with a stick shift to match;
And a purse with no handles, but simply a latch.

Who am I?

UPDATE: Riddle solved by Bronx Richie. See comments for answer.

I’m a sinister southpaw; a portside direction;
The Democrats’ base in the recent election;
How Elvis departed, like any defection;
And items not taken, still there for selection.

Who am I?
