Abstract
The possible association of Galactic globular clusters with the Sgr Stream is shortly reviewed at the light of the most recent observations of the Stream. >= 20 % of the Galactic globular clusters with R_{GC}>= 10 Kpc are found to lie within or very nearby to the Sgr Stream as traced over the whole sky by the M giants from the 2MASS catalogue, in agreement with the results by Bellazzini, Ferraro and Ibata (2003a). Another possible association of outer halo globulars (NGC 1904, NGC 1851, NGC 2808, and NGC 2298) is also noted and briefly discussed.
