  We point out that in the context of ``two-metric'' theories of gravity there
is the possibility that cosmic defects will produce a spectrum of primordial
adiabatic density perturbations. This will happen when the speed characterising
the defect-producing scalar field is much larger than the speed characterising
gravity and all standard model particles. This model will exactly mimic the
standard predictions of inflationary models, with the exception of a small
non-Gaussian signal which could be detected by future experiments. We briefly
discuss defect evolution in these scenarios and analyze their cosmological
consequences.
