Live-blogging OWS daily since October 1.  Email: All times ET.   See my e-book on Occupy "40 Days That Shook the World."   My other books, including new ones on Bradley Manning and Beethoven, here.

12:30 Press release just now in my email box from Occupy Denver:  "On May Day, we are calling on the people of Denver to convene at the Pavillion on 16th st  at 9:30 PM, and we will hold a sleep-in.  By holding a mass sleep in on the 16th st mall, we will stand in solidarity with those who are being singled out by this draconian bill and let its chief backers know, that this is our city, our streets, and no one will be jailed for lack of privilege.  Rather than be forced off the streets by the  Downtown Denver Business Partnership, we aim to show the 1% that a Denver’s Peoples Partnership is stronger than all the lobbyists in the city.  On May Day,  Bring your bodies, your friends, your wares and liberate the 16th st mall with us."

11:55 Good preview of May Day actions in NY tomorrow with accent on "confrontations."   And see top of Nation site right now for special coverage and features.

11:00  NYT on the letters and white substance (corn starch) sent to Wells Fargo and Chase branches and Mayor Bloomberg (see below)…. Claim that several apartments where anarchists live in NYC visited by police today.

9:05 Tom Morello, who is leading a "thousand man" guitar army tomorrow in NY now tweets:  "My new band also looking 4 1million percussionists. Marching band veterans, pots & pans bangers please apply. Noon/Bryant Park."  Big boost for May Day tomorrow as Tom and Ben Harper (who is also leading march tomorrow) will be on Jimmy Fallon tonight, as he tweets:  "Looking for best and worst 25,000 musicians in NYC area. Tomm. Bryant Park. Noon. Nightwatchman/Ben Harper 2nite on Fallon to PUMP IT UP."

6:50  Fox News:  NYPD investigating envelopes with white powder sent to "at least" 5 Wells Fargo branches in city, discovered today.  "The bank branches were closed, and they will remain closed until the situation is deemed safe, the spokesman said."   Fox helpfully notes that this happening on the eve of May Day but does note later that this has not been linked to Occupy (yet).  Of course, Wells Fargo was a target of protests in San Fran just last week.

6:45 Major NYT piece online tonight, presumably in print tomorrow, on Occupy in academia, with new studies, books emerging and so on.

1:10 Famous and good guy author Stephen King begs U.S. to tax him and other very rich more severely.  Strong language and curse words.  Even attacks Koch brothers.   "I’ve known rich people, and why not, since I’m one of them? The majority would rather douse their dicks with lighter fluid, strike a match, and dance around singing “Disco Inferno” than pay one more cent in taxes to Uncle Sugar…. If this situation isn’t fairly addressed, last year’s protests will just be the beginning. Scrooge changed his tune after the ghosts visited him. Marie Antoinette, on the other hand, lost her head. Think about it."

1:00 5 ways to strike, or at least occupy, May Day even if you have to work…Natasha Lennard at Salon on what to expect on May Day, coast to coast….

11:05 Watch David Harvey on Democracy Now! today re: May Day.

As always, any action taken by the workers at their workplace or against their employers will be met with our support and solidarity."

10:05 Springsteen, as part of his record-setitng 2 1/2 hour set at JazzFest in Nola yestrerday, did rousing version of blues classic (later made famous by OWS-backing Ry Cooder) "How Can a Poor Man Stand Such Times and Live."  Watch:

9:15  Just now, from AP:    "Four New York City lawmakers are suing the city over its treatment of the Occupy Wall Street protests.  The civil rights suit was filed Monday in a Manhattan federal court. It says police conduct is so problematic that the force needs an outside monitor.The city Law Department had no immediate comment Monday. Mayor Michael Bloomberg has defended police handling of the protests. Occupy demonstrators have gone to court before over particular episodes. The new lawsuit is a compendium of complaints.  It says the city and police violated demonstrators’ free speech and other rights, used excessive force and interfered with journalists’ and council members’ efforts to observe.  City Council members Letitia James, Melissa Mark-Viverito, Ydanis (ee-DAH’nihs) Rodriguez and Jumaane Williams are among the plaintiffs."
