Real bands cameoing as fictional bands in movies/TV?

I’m still on The Grimleys since it is a rich seam. Here is Noddy Holder’s character talking to the publican played by Alvin Stardust about how ridiculous their childhood dreams of a career in music were. Note Stardust is wearing a leather glove - his real life trademark as a singer used to be wearing all leather including a glove.

And in leather in his pop star glam rock prime

Meanwhile this would be a better fit for the OP. Apparently in the much weaker third and final season punk band UFX (not a band I’m familiar with) made a cameo appearance.
