Bach is the reason I often shortlist
Sebastian.
RE Sebastian in general:
Sebastian is fine, it is very solid and stocky phonetically IMO, and I am tired of the pretentious image BTNers have of it. It is
not a bad name.
Sebastian Adair is fine flow-wise, because
Adair is an iamb and goes well with almost everything, but
Sebastian is so
German (and I guess Spanish and stuff too, but mostly
German to me) and
Adair so Scottish that to me there is a big clash. Plus it seems a bit snooty, as if you'd find him at one of Gatsby's parties.
