Early 1973 finds Raspberries off on a European promotional jaunt. While overseas, the band performs a live concert at the MIDEM Festival in Cannes, France, tapes a high-profile radio show on the Armed Forces Radio Network in Frankfurt, Germany and appears on the German TV show, Hits A Go Go.   Raspberries appear on a variety of national TV shows including American Bandstand, Don Kirshner’s Rock Concert, Midnight Special, Flipside, Go, and The Mike Douglas Show.   Raspberries are back at New York’s Record Plant to lay down tracks for their third album, Side 3.   Side 3 is released and features a tougher, more guitar heavy sound. The album include the singles, “Tonight,” “Ecstasy” and I’m A Rocker”.   The album’s spectacular design -- a die-cut of a basket of raspberries --is cited thirty years later as one of the best album covers in several Album Art rock tomes.   On September 26, Raspberries perform a SRO headlining show at New York’s prestigious Carnegie Hall. In a tongue in cheek nod to the venue’s historic connection with a certain band of longhairs from Liverpool, England, the group open with a snippet of “Ticket To Ride” before launching into “I Wanna Be With You.” Celebrated by band members and press alike as the group’s crowning moment, the concert is witnessed by rock luminaries, Todd Rundgren, Gene Cornish of The Young Rascals and KISS’s Paul Stanley.   Late November sees the departure of members, Dave Smalley and Jim Bonfanti.
