Sammy Hagar & The Circle are keeping their "Lockdown Challenge" going with a new self-quarantine version of the late, great Little Richard's 1958 screamer, "Keep A Knockin'."

Hagar, along with Michael Anthony, Jason Bonham, and Vic Johnson have already tackled versions of Buffalo Springfield's "For What It's Worth," AC/DC's "Whole Lotta Rosie," the Who's "Won't Get Fooled Again," Bob Marley & The Wailers' "Three Little Birds," Van Halen's "Good Enough," and their own original jam, "Funky Feng Shui."

Hagar posted a message to fans under the video on YouTube, admitting, "I had the hardest time with this one because every time I came in singing, I started singing Led Zeppelin 'Rock 'N' Roll'! It took me three damn takes. My favorite drummer and my favorite singer of all time -- love this one hope you do too. Long live the music of John Bonham and Little Richard!

During a recent chat with AXS TV's At Home And Social With Sammy Hagar, the "Red Rocker" shed light on his self-quarantine during the pandemic: "The first month, I was kinda diggin' it, 'cause I've been workin' my whole life. Every day of my life, as far back as I can remember, I had to get up, write a song, go in the studio, go on tour, do an interview, or go to a business meeting, even -- y'know? It's just always, always, always. . . I've been so busy with all my liquor companies, and Cabo Wabos, and restaurants, and bars and nah, nah, nah. . . Two bands, y'know? Three bands (crash in the background). So, I was diggin' it, but now I'm gettin' kinda antsy, I gotta tell ya -- I'm gettin' a little bit bored."
