Fresh Air Weekend highlights some of the best interviews and reviews from past weeks, and new program elements specially paced for weekends. Our weekend show emphasizes interviews with writers, filmmakers, actors, and musicians, and often includes excerpts from live in-studio concerts. This week:

Tucked inside the omnibus spending bill that the House of Representatives passed earlier, today, is a provision that prevents the Department of Energy from enforcing new, more energy efficient standards for light bulbs.

The new standards were signed into law in 2007 by then President Bush, but the standards have become a favorite cause for Rush Limbaugh and the Tea Party, who say the bill would ban incandescent light bulbs and give Americans less choice. They say it is a perfect example of government overreach.

The Republican presidential contest remains fluid less than three weeks before the caucuses and primaries begin. Nationwide, nearly one in five GOP voters is still undecided. And in Iowa, candidates are making their final push before the Jan. 3 caucuses.

Former Massachusetts Gov. Mitt Romney on Friday told workers at a metal fabricating plant in Sioux City, Iowa: "I am running in this race because I understand how to get middle-class Americans prosperous again, working again, buying things, and putting more Americans back to work."

It may or may not be a punt, but the Obama administration wants to let states play a bigger role in deciding what constitutes an "essential health benefits" package when it comes to health insurance.

The Department of Health and Human Services issued what it called a "bulletin" outlining a policy it hopes to impose. In other words, it's not even yet a formal regulation.

The day after the final debate before the primaries, former Massachusetts Gov. Mitt Romney campaigned in Iowa. He also picked up the endorsement of South Carolina Gov. Nikki Haley.

The Arab League has a reputation of being long on rhetoric and short on action. That's why it was so surprising when Arab ministers approved an unprecedented package of sanctions against Syria at the end of November.

But the unity that produced that vote is falling apart, and a meeting in Cairo to set the terms of the sanctions was suspended indefinitely.

Anybody with an e-mail box this time of year is in the middle of a storm — a 20 percent-off coupon lands, only to be topped by another for 30 percent off, then 40 percent, half-price. That's not to mention the free shipping offers piling up like snowdrifts as we head into the last full weekend of Christmas shopping.

It wasn't the fast lane to success for The Black Keys. In fact, the cover of the band's new album El Camino is a convenient reminder of that. The old, beat-up van featured on the front of the Akron duo's latest record is the actual vehicle the group used to tour in its early days. From then until now, The Black Keys' members have earned countless fans through rigorous touring and a strong body of work in the studio.
