It's my guess that The Reaction were named in honour of their Mod forebears The Action. Unexpectedly, Top Sounds has just released a 4 track 10" of unreleased Action/related tracks which includes the best version I've heard them do of Martha Reeves & The Vandellas' "In My Lonely Room" and a fabulously vibrant take on The Tempations' "Why You Wanna Make Me Blue" . There are samples of all 4 tracks at juno.co.uk. Blue eyed soul seldom sounded so convincing or so vital.
