The Duluth Trading Co., which is actually based in Wisconsin, thought it had pretty clever line to promote its pullover shirts:

Don a henley, and take it easy.

Clever, perhaps to everyone but Don Henley and his lawyers. Henley is a founding member of the Eagles, and "Take it Easy" was the wildly popular and enduring band's first hit.

Like many 1970s rock bands, the Eagles don't believe in using their names, brand, songs or likenesses for commercial gain -- particularly without permission. So Henley has sued Duluth Trading Co., in California federal court, as first reported in The Hollywood Reporter.

Henley's trademark infrigement lawsuit contends that many readers of the Duluth Trading Co. ad would think he was endorsing the shirt and the company.

Duluth Trading Co., primarily a catalogue and online retailer, does operate a few stores, including one in downtown Port Washington.

The company told Rolling Stone it had no comment on Henley's suit, according to The Current.
