When the Foo Fighters episode of James Corden's "Carpool Karaoke" premiered back in September, fans of the show and of the band were excited to see them jam to their hits in Corden's car. The 13-minute long segment was filled with laughter, jokes, and of course music, but apparently, it wasn't all that it seemed. In fact, the band recently opened up to NME to share their true feelings about the experience, which they agreed was quite "uncomfortable." Here's why.

Filming took too long

The Foo Fighters episode of James Corden's "Carpool Karaoke" may have been 13 minutes of pure entertainment for fans of the show and of the band, but for the band members themselves, it was quite exhausting.

Foo Fighters guitarist Pat Smear admitted to NME that it took them over three hours to film the entire segment and by the time they finished the third hour, "it got less fun. It kinda went on." The episode also saw Corden and the band drop by Guitar Centre to check out some musical instruments and perform Rick Astley's "Never Gonna Give You Up!" in the studio.

Dave Grohl has no hard feelings towards James Corden

Despite what they call an "uncomfortable" experience, the men of Foo Fighters have no ill feelings towards "Carpool Karaoke" host James Corden. In fact, Dave Grohl told NME that "he's a very nice guy." It was just that singing to one person felt odd to them, compared to singing to sold-out arenas.

US Weekly reported that according to Pat Smear, "Singing other people's songs would have been easier." Grohl agreed, saying that "I could do that all day."

The band isn't the first to feel weird about the segment

Apparently, the Foo Fighters aren't the only ones to have had awkward experiences on the show, as US Weekly reported even Britney Spears admitted to feeling "awkward driving by grocery stores" during an interview with KTU 103.5.

Nonetheless, she did admire James Corden, saying that "The guy was incredibly sweet."

Fighters release new record

The Foo Fighters' episode of James Corden's "Carpool Karaoke" was one of the band's efforts to promote their new record, "Concrete and Gold," which was released on September 15. The new record was produced by Greg Kurstin and was recorded at EastWest Studios in Hollywood, California.

The new record has produced two singles, "Run" and "The Sky is a Neighborhood." The band is currently on tour to promote the recently-released record and are headed for venues in Washington D.C., Columbia, Nashville, Memphis, and New Orleans this month.
