What about early Who? There early stuff wasn't that heavy or too bluesy either. More 'power pop' to quote Pete Townshend. Not sure if it would be compatible lyricaly though, so maybe not that good a suggestion I suppose.
Here's a few groups from the 1st British invasion for you though;
The Rolling Stones, The Yardbirds, The Who, The Kinks, The Pretty Things, Dusty Springfield, The Dave Clark Five, Peter and Gordon, Chad and Jeremy, and Manfred Mann. Manchester had The Hollies, Wayne Fontana and the Mindbenders, Freddie and the Dreamers, and Herman's Hermits; Newcastle had The Animals; and Birmingham had The Spencer Davis Group (featuring Steve Winwood) and The Moody Blues. Bands sprang up from Belfast, Them, with Van Morrison to St Albans, The Zombies, with more inventive artists arriving to keep the syles moving forward, including The Small Faces, The Move, The Creation, The Troggs, Donovan, and John's Children.
I copied that from wikipedia, quite a few groups but it might point you in the direction of something you wouldn't have thought of
Blind acceptance is a sign, of stupid fools who stand in line. John Lydon.
'Mod' is a shorter word for 'young, beautiful and stupid' - we've all been there." - Pete Townshend.
