  The membership of Matsunaga's variable 1, a carbon-rich, mass-losing, Mira
variable, in the globular cluster Lynga 7 is discussed on the basis of radial
velocities. We conclude that it is a member, the first known C-Mira in a
globular cluster. Since such a variable is expected to have an age of $\sim
1-2$ Gyr and an initial mass of $\sim 1.5$ solar masses, we conclude that this
star must be the product of a stellar merger.
