   Graphics3D@ p1,
   Graphics3D@ p2 /. h_Hue -> SurfaceColor[h],
   Lighting -> True]


   Graphics3D@ p1 /. p_Polygon -> {Hue[2/3], p},
   Graphics3D@ p2,
   Lighting -> False]

Either way one of the plots has to be modified, because originally p1 uses  
the simulated lighting and p2 doesn't. Another method is to use  
ParametricPlot3D, which accepts a list of plot objects.

I think some of the details on using graphics (graphic details?) are not  
very well documented; for example, ColorFunction help page says: "In  
three-dimensional graphics, ColorFunction is used only with the option  
setting Lighting -> False." However,

Plot3D[{x^2 + y^2, Hue[0]}, {x, -1, 1}, {y, -1, 1},
   ColorFunction -> (Hue[2/3]&), Lighting -> True]

plots using Hue[2/3], not Hue[0].
