Went to see Patti Smith at The Tate Modern, where she gave a a poetry/song performance to support the Robert Mapplethorpe exhibition at the Alison Jacques Gallery. All very NYC arty - a couple of films, one , "Still Moving" a RM/PS collaboration from the mid 1970's - then Patti got on stage for some anecdotes,poems and songs. A bit under rehearsed and scatty - but most enjoyable.
