  We show that dynamical evolution in a strong (Galactic Centre-like) tidal
field can create clusters that would appear to have very top-heavy IMFs. The
tidal disruption of single star forming events can leave several bound
`clusters' spread along 20 pc of the orbit within 1-2 Myr. These surviving
(sub)clusters tend to contain an over-abundance of massive stars, with low-mass
stars tending to be spread along the whole `tidal arm'. Therefore observing a
cluster in a strong tidal field with a top-heavy IMF might well not mean the
stars formed with a top-heavy IMF.
