I agree with this. Change in line ups where great for Motorhead. Every line up continued where old one stoped. And new line up new sound and it is still Motorhead, that's great. In some bands change of line up doesn't work but for Motorhead I think it couldn't be better. Motorhead is much more better today because of this line up changes. Can you imagine Lemmy/Larry/Lucas playing still today? Or Kilmister/Clarke/Taylor? It would be much more boring Motorhead and with less progress.
Lemmy: "We are Motorhead and we play rock 'n' roll!"
