It can't be worse more than vol 1. But it is true, again Lemmy have problems singing, inside song you can hear when Lemmy sings song become little bit slower than instrumental part of the song is little bit faster almost normal. However, I think this will be better than vol 1. Older they are worse they will be, that's normal. Only thing is time when Lemmy will say: Ok that's it. Retirement.
Regarding Lemmy's voice, to me the older the voice or the rawer/dirty the sound is the better. Like listening to those old 76-78 bootlegs, the quality is bad but I just love it. I don't care if the voice doesn't catch up, of if he misses some words (like an old punk lol), or if Phil doesn't do a solo line, that's fine by me, I just want it raw, dirty, fast, loud and if possible good number of songs per concert, something like over 19 songs.
