We employ a combination of chemical substitution and angle resolved photoemission spectroscopy to prove that the Fermi level in the {gamma} band of Sr{sub 2-y}La{sub y}RuO{sub 4} can be made to traverse a van Hove singularity. Remarkably, the large mass renormalization has little dependence on either k or doping. By combining the results from photoemission with thermodynamic measurements on the same batches of crystals, we deduce a parameterization of the full many-body quasiparticle dispersion in Sr{sub 2}RuO{sub 4} which extends from the Fermi level to approximately 20 meV above it.
