Glenn Frey and Joe Walsh (both center) perform at the 1998 NACDS Annual Meeting.

The National Association of Chain Drug Stores joined the chorus of tributes for Glenn Frey, the co-founder and singer/songwriter/guitarist for the hit rock band the Eagles, who died on Monday at age 67.

In a blog post on Wednesday, NACDS noted that Frey performed at two of its conferences, in 1998 and 2007.

NACDS senior VP of member programs and services Jim Whitman also shared an anecdote in the posting. Before the 1998 NACDS Annual Meeting, he said Frey and fellow Eagles guitarist Joe Walsh asked about the event and the audience. Whitman told them, “It’s a big deal for us. It’s black tie.” And sure enough, the band donned suits and tuxedos for the concert.

Entertainment is a key ingredient of NACDS events, according to Whitman. He said Frey and Walsh were chosen because they would appeal to the audience and “they’re leading examples of what’s good in rock and roll.”
