Snape the Gryffindor or Ravenclaw?!

Is there actually any canon stating Snape was in Slytherin? I do not
have my books handy. I know Sirius said that Snape hung out with an
older group of Slytherins, but is there actually CANON stating Snape
was IN Slytherin? I do not think one would have to have been in a
particular house to be head of that house as a staff member. In know
JKR was asked about the house affiliation of MWPP, but what about
Snape?

Lynnette, who thinks Snape IS a good guy, even if he is NOT a nice
guy!
