I have just spent 5 minutes trying to get this damn printer to print an envelope without mangling it. Wonderful.

THIS AIR BED IS GREAT! I HAD PREVIOUSLY PAID WAY MORE FOR THE "A--O" BRAND, BUT THIS ONE IS EVERY BIT AS GOOD AS THE MORE EXPENSIVE ONE. I AM A GAL WITH A "MATURE" FIGURE, AND IT (TWIN) ONLY LOST A LITTLE AIR. WITH THE ELECTRIC PUMP, NO WORRIES! JUST A HINT FOR SOME OF YOU WITH BAD KNEES LIKE I HAVE....I PLACED TWO CAMP COTS SIDE BY SIDE AND LAID THE MATTRESS ON TOP. PERFECT FOR THESE TIRED OLD KNESS AND BODY TO GET UP AND OFF OF. KUDOS ON THIS AIR BED!

This self-titled effort from the British band offers their masterful harmonies on an eleven track album.The trio of Allan Clarke, Tony Hicks and Terry Sylvester share most of the compositions, with the exception of the album's biggest hit, THE AIR THAT I BREATHE, written by Albert Hammond.The only real misstep is the obvious LONG COOL WOMAN clone, THE DAY CURLY BILLY SHOT DOWN CRAZY SAM MCGEE, which even copies LCW's opening guitar riff. However, the remaining tracks offer enjoyable examples of the Hollies vocal and musical expertise.In addition to the aforementioned AIR, I like the airy mystique of PICK UP THE PIECES, the harmonic rock of IT'S A SHAME IT'S A GAME, TRANSATLANTIC WESTBOUND JET, and DON'T LET ME DOWN. Ballad-wise, DON'T LET ME DOWN is sharp and the 50ish doo-wop sound of LOVE MAKES THE WORLD GO ROUND is a nice change of pace.Overall, an enjoyableslice of 70s pop.
