With Jon [Davison] tied up with his other band he cannot perform live with us at present.  It seemed odd to move forward having him front the band on this album only to have Carl Groves fill in for him on stage.  So Carl will be the primary male vocalist on this album.  Jon will sing on this album, but his role is limited.  Susie Bogdanowicz will also return [...] It’s our twentieth year of recording as Glass Hammer – so we thought it would be fun to combine singers from different eras of the band.  Still, Carl Groves is handling most of the lead vocals.

I think we will definitely continue on working with both guys [Groves & Davison]. We talked about that while we were on the cruise [to the Edge]. I got to introduce Carl to Jon. We're tossing around a lot of ideas right now. We certainly want to keep Carl in the group. Susie [Bogdanowicz] might make a reappearance someday. And Jon, of course, is going to work with us, too.

Yes is a time-consuming job. [...] I'm not sure how that's going to effect things. [Davison]'s welcome to contribute, and if he has song ideas, we're always ready to work with him. Bringing Carl back in, there may be a chance for him to contribute. We're right now beginning to compose music for a new album. It remains to be seen how much each person will play a part.
