With the deadline to file taxes looming, some event hosts may see a drop-off in R.S.V.P.s among the procrastinating set. Determined not to let their event suffer that fate, irreverent Jewish-interest mag Heeb brought accountants to its Hollywood issue party last night to offer consultations for guests. The invitation read, "Accountants on Premises: Bring Your W-2s (Not Kidding)." The party took over the new Gallery 819 space at Von Dutch, and featured a performance from L'Amour Est La Guerra.
