The band Hanson paid tribute to their music talent agent Dave Shapiro after he was named as one of those killed in the San Diego plane crash on Thursday.

Shapiro, co-founder of Sound Talent Group, and two employees were among those killed, the music agency said in a statement.

“Today we are all mourning the tragic loss of our longtime friend and booking agent Dave Shapiro,” Hanson said in a post on X, formerly Twitter.

“Dave was fearless in life, and tireless in his work, and the kind of friend you would want on your speed dial. Dave seemed to always be working on a new endeavor, or to be going on a new adventure, because he was always excited for a new challenge.

“We are grateful for the 15 years we knew him. Our hearts go out to Dave’s family and the team at Sound Talent Group.”

As well as Hanson, Sound Talent Group has represented artists including American singer-songwriter Vanessa Carlton and the Canadian rock group Sum 41.

Hanson is perhaps best known for its earworm 1990s pop hit, “MMMBop.” Shapiro also owned Velocity Records.
