[Avodah] Lecha Dodi

[Rich, Joel]

Can anyone supply any information as to how Lecha Dodi became almost universally adopted a part of the Friday night davening?  Surely there must have been opposition to this "new innovation" at the time when it was introduced. Can anyone steer me to some historical sources. or something on the Internet?

Many thanks in advance.

Listen here where R' Kaplan quotes R' Shach as saying it started by R' Alkabetz in one shul (which apparently is allowable) and spread from there?
