Yardbird drummer Jim McCarty mentions possibility of band's April 1968 studio session seeing legitimate release: Q&A: Jim McCarty Discusses the Yardbirds’ Legacy | » It came out as a quasi-legal CD about 16 years ago, i.e. "Cumular Limit" before being withdrawn. It had the blessings of Keith Relf's widow, April, as well as McCarty and Chris Dreja. The songs were recorded in NYC a few days after their Anderson Theater show (released in 1971 as "Live Yardbirds! Featuring Jimmy Page"), but were not released at time. Bill Wyman makes mention of Jimmy Page playing them to him in his autobigraphy, saying the sounded nothing like the Yardbirds of the past and how excited Page was by the songs. Fast forward to circa 2000 or a a while earlier. Bob Irwin unearthed the multitracks and did a quick mix that was never intended for commercial release (ownership of the original sessions has been debated for years now; they had just left Mickie Most and hooked up with producer Manny Kellem - if you don't know his resume, goggle it! Even more ill-suited to the Yardies than Most was... Sheesh - so, RAK, Epic and Columbia as well as Page and the other surviving Yardies all can make some sort of claim)... Said rough mixes then came out as "Cumular Limit"... All that is except for "Knowing That I'm Losing You," which is a nascent version of "Tangerine"... It was supposed to be included but the record company and McCarty & Dreja got cold feet at the last moment, knowing of Page's interest in said song... In a 2012 "Rolling Stone" interview, Page made mention of how he had been listening to the Anderson Theater tapes (which Epic returned to him in the late '70s) and how he wanted to remix them (without overdubbed cheers)... So, one can dream of the Anderson show and final NYC sessions coming out!
