This is a beautiful copy of one of the group's pre-"Sherry" singles, before they signed to Vee Jay. The A side is a fairly straightforward uptempo doo-wop, with Frankie Valli's vocals just part of the harmony. The flip, however, clearly shows a step toward "Sherry," with a similar drum intro and Valli on lead vocals. He's not singing with the falsetto that made him famous, but that would come soon enough. :-) Apparently, there were three pressings of this single, and this is the second one, with "A Bob Crewe Prod." on the right side of the label.
Note: This single is from a large collection we've purchased whose records typically have mint or near-mint audio and near-mint vinyl. The labels are near mint as well, but the owner had a habit of writing a date in small print on the B side label. This single also has a drillhole (see scan).
