When Exactly Did Bob Welch Leave Fleetwood Mac?

[WalkAThinLine.]

Most accounts list the generic December 1974 as his departure date, but I'm curious exactly what day he left the band and when the band mobilized to recruit Lindsey and Stevie. Welch's last performance with the band to my understanding was December 15, 1974, so that provides roughly a two week time span of when he could have departed. Based on certain accounts, Mick contacted Keith Olsen around New Year's Eve to receive Buckingham's phone number, so I'm thinking that Bob's departure was later in the month.
