"When You Walk in the Room" is a song written by Jackie DeShannon. Who did an earlier v of Needles and Pins
I think she also wrote "Each Time", another song the Searchers did [LP cut, maybe also a 'B' side]. Great guitar work.
She did the original version. The Searchers cadged it in Hamburg, after hearing Cliff Bennett and the Rebel Rousers doing it in their stage act. The bass player for Cliff was Frank Allen, who replaced Tony Jackson in the Searchers in '64 - just in time for "When You Walk in the Room"
