You almost got it right, David. But the top one is Schumann's 4th, not 1st. Last movement, to be precise. As played by Cleveland Orchestra, conducted by George Szell. The bottom one comes from Beethoven's 2nd, indeed. Performed by Berlin Staatskapelle, conducted by Barenboim (you like these details, don't you, Colin? :cheers: ).
The similarity is striking. Wonder if it's purely coincidental...
