The Clash Sues Wilson Over Its 'Clash' Tennis Rackets
Andrei Mincov's commentary on the original article
Goods and services are different. Classes are different. The Clash's trademark is very limited. Also, The Clash allowed another entity to register the trademark CLASH for workboots, in the same class 25. Doesn't look like The Clash's chances of winning this are much higher than a snowball's chance in hell.
