I'm Tellin' You Now by Freddie & The Dreamers

"I'm Telling You Now" is a song by Freddie Garrity and Mitch Murray, originally performed by Freddie and the Dreamers, that hit number one on the American Billboard Hot 100 in 1965. Murray also wrote songs for other British artists during the 1960s, including Gerry and the Pacemakers, Manfred Mann, and Georgie Fame. "I'm Telling You Now" was first released in 1963 on Capitol Records, USA/Canada and on Columbia, UK/India/Netherlands/Sweden, but was not successful. Two years later, Capitol's subsidiary, Tower Records, re-released the song, which became extremely popular and propelled Freddie and the Dreamers to pop-music stardom. The dancing by Freddie and the band during this song spawned a minor dance fad, The Freddie.
