1970: Janis Joplin appears with her old band, Big Brother & the Holding Company, at a special reunion concert in San Francisco. It will be the last time she appears with the band.

1964: “The Times They are a-Changin’” indeed. It was on this day that Bob Dylan made his first appearance on the pop charts when his song, “The Times They Are a-Changin’,” entered the UK charts. Just one day later, Dylan’s “Subterranean Homesick Blues” would enter the U.S. Top 40.

1967: Having recently left the Spender Davis Group, keyboard player/singer/composer Stevie Winwood joins Dave Mason, Chris Wood and Jim Capaldi to form a new band they call Traffic.

2008: To celebrate April Fool’s Day, soon-to-be-disgraced Illinois Governor Rod Blagojevich declares the day “Cheap Trick Day,” honoring the band that originally hailed from that state.

No word on how much the band had to pay the governor for that honor.

1957: If you had to pick just one song to encapsulate everything that is rock & roll, that song would probably be “Johnny B. Goode.” Chuck Berry released that classic on this day. Surprisingly, it did not reach #1 on either the pop or the R&B charts.

1957: Buddy Knox hits #1 on the Billboard Hot 100 with “Party Doll.”

What makes that special? Knox was the first rock singer to hit #1 with a song he wrote himself. He would not be the last.

2001: A 3-hour all-star tribute to Brian Wilson is held at Radio City Music Hall. Billy Joel sings “Don’t Worry Baby” and Paul Simon performs “Surfer Girl.” Others who appear included Ann and Nancy Wilson of Heart, Carly Simon, David Crosby, Jimmy Webb, Elton John, the Go-Go’s and Wilson Phillips.

Brian himself joins in on the finale.

1996: Phil Collins announces his intention to leave the band Genesis where he had served as drummer and lead singer.

2017: Genesis announces they will reunite for another tour.

1979: Eric Clapton finally gets “Layla.” It was on this day that the guitarist married Pattie Boyd, ex-wife of his best friend George Harrison in a ceremony in Tucson, Arizona.

Harrison attends the wedding as do Ringo Starr and Paul McCartney.

Eric and Pattie would divorce 9 years later.

On this day recording studios were busy. Here’s who was recording what:

1957: Ricky Nelson “I’m Walkin’”

1958: Eddie Cochran “Summertime Blues”

1964: Chuck Berry “No Particular Place to Go”

1974: Dionne Warwick & the Spinners “Then Came You”
