I think we all can agree that musical episodes are a bit passé these days, but if there's one show that can still pull it off, it's gotta be Eureka.

Syfy's quirky series already has that whimsical tone and vivid color palette we're used to seeing in Hollywood musicals; so it comes as no shock that Eureka will feature a two-part musical episode next season.

Eureka's Deputy Lupo, Eric Cerra, dropped the news in a recent interview with Sci Wire about the show's upcoming fourth season. Cerra complimented the singing voices of co-stars Joe Morton, Salli Richardson-Whitfield, and Colin Ferguson, but admitted that she has some trouble carrying a tune herself. "... I don't sing. I can't, and I don't, so I'm going to have to take some singing lessons. I'm a little nervous," she said.

Cerra also confirmed what our own Jason Hughes reported last month, Eureka's fourth season will be its longest yet with 22 episodes. Season three concludes Friday, Sept. 18.

Bill Lawrence, Sarah Chalke, and Zach Braff held a lunchtime session to promote the Scrubs musical episode. Lots of funny lines and good information came out of it, but if you read our interview with Lawrence, you heard most of it already (he even quoted from our interview -- at least I think he did -- during the session). But he did offer two new pieces of information, about his current show and his "other" show, Nobody's Watching:

First, the guys from Nobody's Watching will do a 30-minute live special for NBC, where they may pretend to take over the network for 30 minutes. Stay tuned for more information on that.

As far as the Scrubs musical episode is concerned, Bill told me that the songs from the episode will be made available on iTunes, essentially so Touchstone can recoup some of the costs of the more-expensive-than-usual episode. So if you like "Guy Love," you can have it on your iPod for all eternity, likely starting tomorrow.

It doesn't take much to get Scrubs creator Bill Lawrence going. I fully intended to speak to him only about his show's musical episode, which airs tomorrow at 9. But Bill managed to launch into monologues on current shows, the network testing system, Scrubs' weird history, and other topics. But he dropped a lot of interesting information, some of which I mentioned a couple of days ago.

For a guy who isn't quite 38 yet, Lawrence has had quite a successful career. He already has two long-running shows under his belt (he co-created Spin City in 1996), and has been involved in a number of other series. Included in his credits is the Internet phenomenon Nobody's Watching, which scored an NBC development deal after the pilot was "leaked" to YouTube.

After the jump is the freewheeling phone interview I conducted with Lawrence last week. Keep tuned to TV Squad for a Scrubs set visit video, which will be posted next month.

Before I left for Los Angeles, I got on the phone with Scrubs creator and executive producer Bill Lawrence to talk about this coming Thursday's musical episode. What I got was a pretty wide-ranging interview about Scrubs, his other project, Nobody's Watching, the evils of network "testing," his opinions on other shows, and a bunch of other stuff.

He's pretty sure that the show will come back for a seventh season. "It's becoming apparent that it'll be up to us if the show is on again this year, so we'll do one more year," he told me. "Again, the same as last year, I came into this year going 'Ah, it's the fucking last year of this show,' and now we're downstairs scrambling because our studio is like, 'This isn't the last year.' So now we have to re-outline all the stories and change it and all that shit."

Because Zach Braff has mentioned that this season might be his last, I asked Lawrence if a seventh season will include Braff. "I think I'd only do the show with Zach, personally," he said.
